Three grueling weeks of training have past. Everyone has become stronger, both mentally and physically. The one with the most improvement however would be Issei. His body has become noticeably toned. He is no longer a feeble looking twig. But He is still on the smaller side. Additionally his control of Ddraig has increased exponentially.

The next person with the most surprising growth would be Koneko. She has begone to understand her powers more, but she is still reluctant to use it. Her speed has dramatically improved and her hand to hand combat become even more of a threat. She even learned some techniques from Vesta.

Next up Kiba, his reaction speed has sky rocketed due to Mordreds fighting style and her barrage of unrelenting attacks. His swordsmanship has became something to admire because he was trained by an incredible knight . He also became more durable because of Mordred treating him like a rag doll and breaking quite a lot of bones.

Asia is now more confident with her healing. She can heal more than one person at a time now due to the guidance of Jeanne. Also, whenever she does heal just one singular person, it has become so unbelievably potent. She can even send out some low to intermediate level attack magic if it is needed.

Rias and Akeno have improved the least due to their already large amount of power. Nonetheless they were still able to grow in strength. Akenos lightning magic has become way more potent and she even learned a area of affect spell caused by Angels constant hazing. Rias has developed all around. Her already great power has become even more devastating .

All in all this was great training for everyone, but they still need to get past one more trial. They need to fight their temporary mentors one last time.

——-

The dark forest is seen once more and many trees are on the ground. Fallen due to the power of Issei and Y/n.

Y/n crosses his arms and starts examining Issei.

Y/n: "You have come a long way Issei. I can no longer treat you as weak." He says with an approving smile.

Issei: "Thank you Y/n." He says looking down at his arms "I feel so much stronger. This is all thanks to you." He says now clenching his fists.

Y/n nods.

Y/n: "You put in the work Issei, do not forget about that." He speaks "Now, show me how much you have truly changed." He says getting in a stance and motioning Issei to come forward.

Issei complies, and Ddraig appears on his arm while the gem shines brightly.

Ddraig: "BOOST BOOST BOOST BOOST BOOST BOOST BOOST."

Issei closes in on Y/n and right before he gets there he stops. Issei brings up Ddraig to be eye level with Y/n, and he lets the green energy that has been charging up explode. The beam flies towards Y/n and his eyes widen.

Y/n evades the attack just in time, but a few hairs are seen in the air. Y/n quickly surveys the area and Issei is no where to be found. The black haired boy senses something and he looks upward to see Issei in the air. His fist retracted.

Issei brings his fist down right into Y/ns face. Spit soars out of Y/ns mouth and he is sent face first into the earth. Issei lands back on the ground and rolls. He then rushes towards Y/n who stands back up staggering.

Issei who is now face to face with Y/n lowers his fist and brings it back up, uppercutting the other boy. This powerful punch causing Y/n to float up in the air for a bit.

Ddraig: "BOOST BOOST BOOST BOOST BOOST."

The green energy forms off of Isseis arm and bursts Right towards Y/n. The black haired boys eyes are shut, and as the energy beam gets closer his eyes flare open. The second they open he disappeared.

Issei looks at the blast, he noticed it didn't hit Y/n and looks for him frantically. Y/n reappears right behind him ready to throw a punch. Issei noticed this and as Y/n throws the punch he ducks causing Y/n to be unbalanced. Issei uses this to his advantage and grabs his shirt and throws him.

Y/n hits the ground hard. Issei immediately goes for another punch, aimed right for his face. This is the finisher.

The punch is caught by Y/n, a huge smile on his face appears.

Y/n: "You really have become stronger." He says twisting Isseis arm and standing back up.

A hideous red and black aura forms around Y/n. He uses the arm he has to hurl Issei forward. Issei crashes through a couple trees and expects Y/n to chase after him, but nothing ever happened. Issei quickly stands up and looks for Y/n, but he sees him in the spot he was originally. He was looking down at the ground, and small beams of sunlight illuminated the area around Y/n. The light was enough for Issei to get a look at Y/ns face. It was absolutely horrific.

His face is in a wide grin, the blood red mark on his face expands slowly like a parasite, and one of his eyes became a black and red swirl.

Issei: "Y/n?"

Y/ns face immediately snaps towards the sound of Issies voice. He starts to slowly walk up to him with his grin still wide and his head bobbing back and forth. He looked completely deranged.

Issei starts to look freighted, however he still walked towards the seemly bloodthirsty Y/n without a second thought.

As they get face to face Y/n towers over Issei. The black haired boy stared at Issei and the other boy stares right back. Issei looks at the dead eyes of Y/n, but he doesn't budge. He stands his ground.

Seeing this Y/n grabs Issei by the neck and lifts him up. Issei tries to fight it but he cannot get out of his grasp. Y/n once again stares at the ground.

After while and Issei kicking around crazily Y/n looks back up and his expression softens. His mark retracts and his eye returns to normal.

Y/n: "You've passed." He says letting Issei fall to the ground.

Issei lands on his butt and a confused look dawns on his face.

Issei: "Uh, what?"

Y/n: "You heard me, your training is is finished." He says simply "I wish I could say that I have nothing else to teach you, but that's simply wrong. However in this short amount of time you have become quite the force to be reckoned with." He explains "Your body has toned, you have more control of Ddraig and finally intimidation has little affect on you. I can approve of you. Issei, The New Red Dragon Emperor." He says smiling as Issei looks in awe at him.

——-

The open field is in view with divots all in the ground and Rias, Akeno and Angel are shown.

Angel examines the two girls and a slight smile appears on her face.

Angel: "You two have surprised me. Your already powerful magic has become even more devastating. I might even have to go full out." She says mockingly.

Rias: "I mean, I sure would hope so. That would definitely put a dent in my pride." She says laughing nervously.

Akeno has a look of agreement on her face.

Angel starts laughing a bit.

Angel: "I guess we will just have to see how much power you can bring out of me." She says smiling.

Rias and Akeno look at each other and nod. They immediately start to conjuring up some magic. Akeno lighting starts to form all around her body and she begins floating up in the air. And Rias starts to form a black and red circle made out of her magic.

Angel looks at them with a smirk. She disappeared without a trace. Rias and Akeno however stay calm.

Angel reappears close to the other girls with her own beam of magic. This being a white ball with small swirls of black mixed into it. She lets the giant beam go directed straight towards the two girls.

The other two who where powering up look towards the direction of the cat girl and send their charged up abilities towards Angel.

White, red, and blue energy clash. At first angles white and black magic starts to over takes Akenos and Rias's but after awhile it was just too much. The blue and red energy overtake the white.

Angel evades the oncoming blast and it's in wake was a gigantic hole that seemed like it was never gonna end.

Akeno lands back on the ground softly and Rias looks at her with a smile.

Angel noticed they were slacking, so she used her magic to turn invisible and creep up on the two unexacting teenagers.

The first one she attacked was Rias, since she was the more powerful of the two. She sweeps the red haired girls legs out, which causes Rias to fly into the ground. Akeno immediately starts to look around for the attacker. However she is meet with nothing, right until she gets a kick right into the face. With a yelp Akeno flies backwards.

The two are now separated, which makes it easier for Angel to pick them off. Angel turns visible once again and rushes towards Akeno since Rias looks incapacitated for now.

Akeno lands back on the earth with a loud crash, but she shakes it off quickly and stands back upright. She looks for the black cat and sees a blur coming right towards her. Akeno then fires some lighting at the blur rushing at her. Angel dodges but Akenos magic is unrelenting.

Akeno stops the unrelenting attacks for a second, but then hundreds of lighting bolts appear in the sky. All aimed at the black cat. Angel looks up and sees all of these and her eyes widen. Nonetheless she continues the frontal assault.

Akeno let's all of bolts go, and they come crashing towards angel at terrifying speeds. The impact of these bolts make the ground shake. Seeing this carnage the black cat begins to smile and then she speeds up. Angel is no longer a blur, she just completely disappears.

Akeno looks at the many huge holes in the ground with approval. However she still looks for Angel, knowing she could be anywhere. But after awhile she begins to let her guard down.

And that's when Angel strikes.

She appears behind her with a black and white magic ball conjured and sends it flying towards Akeno.

The black haired girl senses the magic flying towards her and tries to evade it, but it still nicks her. This is enough damage to count her out of the fight and she is shown on the ground unconscious.

Angel nods and starts walk towards her body, she makes it to her and smiles knowing she put up a good fight.

However as she's looking down at Akenos body, a gigantic blast of bright red and black energy comes soaring at the expecting cat. She looks at the blast and her eyes turn wide. But then a tiny smile appears on her face. She has a look of approval as the blast comes closer.

The blast finally hits her and she is sent backwards. She lands back on the ground unconscious.

Rias is shown dirty, battered and limping. But still making her way towards the unconscious Akeno and Angel. She then looks down at the limp cat girl and smiles. Rias falls to her knees and passes out.

——

Vesta and Koneko are shown in the familiar mountain range by the cabin with many dents in the ground. Both looking serious and not one word is exchanged.

They both look at each other and nod. In unison they rush at each other both with firsts up.

Koneko goes for the first punch, Vesta dodges it just in time. Wind picks up at the end of Konkeos fists and Vestas hair sways in the wind.

Koneko immediately tries to go for another attack but she is met with nothing but air. She looks down and sees Vesta low and ready to shoot for her legs. Konekos eyes widen.

Vesta lunges for the single leg of the cat girl but Koneko puts her legs back and sprawls. The white haired girl stuffs Vestas horned head into the earth, not letting her reattack.

Vesta understands the position she is in, so she circles around Konekos leg putting more and more pressure into it, causing a yelp out of Koneko. Vesta now has more control over Konkeos leg, so she brings it up and the white haired girl is now hopping on one leg while Vesta has the other.

Vesta flips Koneko, making the other girl do cartwheels. After a few cartwheels Koneko springs off her hands and does a few flips in the air.

Vesta notices the moment of weakness with Koneko being in the air, so she sprints towards her. The cat girl is just about to land until Vesta immediately sweeps her legs. Causing the white haired girl to slam into the ground.

Vesta goes for a punch aimed right at the nose of Koneko, however she spins out of the way. She then quickly twirls back up on her feet, flailing her legs trying to get an unexpected hit on Vesta. Nothing lands much to Konekos distaste.

The two girls look at each other, both of them circling each other and analyzing each other's movements. Once again they both charge at each other with their hands up and ready.

Blows exchange between the two of them, the two of them relentlessly pummeling the other. Their fists move faster and faster, until only after images of them are seen. This goes on for minutes, until their fists start to slow down.

Koneko was the first to jump out of the brawl. Her face was bruised beyond belief and her clothes are all ragged and torn up. Her breath was shaky and her eyes looked distant.

Vesta on the other hand was not all that hurt. She did have minor bruises and scratches over her body, but her clothes were only slightly dirty. This is the durability of a being that has lived for many eons.

Koneko starts to clumsily walk over towards Vesta, her form is that of boxer once more. However she is barely standing up.

She gets close to Vesta and launches her first at the horned girls. However before it hits the face of Vesta she falls face first into the dirt.

The snake girl looks at other girl beneath her and smiles proudly.

Vesta: "You have grown my child. Now rest up, your gonna need it." She says patting the head of Koneko.

——

The sliver haired female and the blonde boy are shown in a meadow with many holes, creators and cuts due to the battles fought.

Kiba and Mordred have their swords pulled out and both are circling each other. Analyzing each others movement.

After a few minutes and not one word spoken Morded breaks it. She bulls rushes the blonde boy and adjusts her grip on her sword. She thrusts right towards the chest of Kiba.

The blonde boy spins away swiftly. His footwork is absolutely beautiful. Not one single step wasted. As he's spinning he tries to get a sneak attack in on Mordred, but she parries.

Sparks fly between the two swords, and the gray eyes of Mordred meet the light blue eyes of Kiba.

Kiba stops twirling and is now ready to fight once again. This time Kiba initiates the attack. He runs at Mordred who is currently holding her ground. He quickly changes his grip on his sword and hurls a overhand cut.

Mordred parries the blow once more and immediately counters it with a upward slash.

Kiba parries this attack. The two swordsman trade blows pack and forth. Each parrying the others attack beautifully.

This goes on for quite a long time and it starts to become a somewhat of dace between the two. It was something mesmerizing. Absolute stunning swordplay was shown in this battle.

However, as unfortunate as it is this dazzling display of swordsmanship could not last forever. One of the two would have to forfeit. And the one backing out would be Kiba.

His breathing was ragged, he has begun to tire out. Mordred on the other hand still looks ready to go. Kiba smiles at this, the unrelenting will that Mordred has always keeps Kiba fighting. He doesn't want to disappoint her.

So once again Kiba charges towards Mordred. A smile on his face and sword by his side. He performs a upward slash directed towards Morded. One that looks like a crescent moon.

Mordred quickly dodged, and tries to reattack but she notices Kiba cannot be seen. She frantically looks everywhere while her sword at the ready. Then at the last second she notices a sword flying towards her. Once again she sidesteps and perpares for another attack. However she is met with nothing.

This makes the sliver haired girl raise an eyebrow. So she walks towards the direction of the sword and she sees Kiba on his knees. His eyes are closed and a bright smile has appears on his face.

Mordred sees the boy slumped on the ground and chuckes to herself. She pats the boys head and smiles.

Mordred: "You did great kid."

(Sorry for the shorter fight between these two. Swordplay is hard to write lol.)

——

Back at the summer house Asia and Jeanne are shown preparing for everyone to come back injured. And after awhile like they had thought bodies came flying through the front door. Every single one of them looking injured and some of them even being passed out.

Asia rolls her eyes and immediately begins attending to the injured. Jeanne on the other hand was just staring at her master, who seems to have his clothes dirtied. He has not a single scratch on him but Jeanne has never once seen her masters clothes dirty. And she also notices the smile Y/n has while looking at Issei.

This caused Jeanne to have a smile of her own. She was happy that her master seemed joyful.

—————————————————————
(Timeskip.)

It's been a day since the fight between the students and the mentors, and today was the day of the rating game. They have since left the summer home and are now in the occult research club. Everyone has been healed up and they all seem ready to fight. They are all huddled up by Y/n who seems to have a few words for them.

Y/n: "You all have gotten strong. That is a thing I cannot deny." He speaks "You all have surprised me with your determination to no longer be weak. And that is a great thing to have." He explains "However you still need to beat Riser, and I have faith in you all. So do not fail me. Understand?" He says as Rias's peerage nods.

Y/n looks at them with satisfaction, but suddenly a magic circle appears and Riser appears out of the blue with a crooked smile on his face.

Riser: "Is my wife ready to entertain me?" He asks sneering

Rias looks at him with disgust but unfortunately walks towards him, and her peerage trails. They all look at Y/n and he gives them a nod.

Riser then gives Y/n a disgustingly wide grin.

Riser: "You can come too and watch me beat on your precious girlfriend." He says grabbing Rias and hugging her, much to the redheads distaste. "I bet it'll be quite the show." He says as they all disappear in a flash

Y/n: "Well, I guess we have no other choice." He says as the rest of his peerage nods

———

Y/n and the rest of his girls make it to the rating game stage, where many people are shown to be watching. Y/n eyes the crowd carefully.

Aurora:"Master, remember your manners."

Y/n: "Yeah, my fault Aurora." He says sighing.

The girls look at him with concern on their faces. They can tell Y/n is quite stressed. But there is not much they can do about it.

Mordred however gets the bright idea to lay on his shoulder. Much to Y/ns surprise.

Y/n: "M-Mordred?!" He yelps.

Mordred: "Relax master, they will be just fine...I hope." She mutters.

Y/n laughs a little and turns towards the rest of his peerage, who all look a little jealous. Y/ns eyes roll.

Y/n: "Stop looking so sad, you guys can lay on me as well if you want." He says as their eyes light up.

Jeanne takes the other shoulder, Angel who is in her cat form lays on Y/ns head, Aurora sits on his lap and wiggles a little and Vesta tries her best to squeeze in but she cannot.

Vesta starts to pout and Y/n looks saddened. Y/n then manages to convince Aurora move over a little so Vesta can sit there as well. Since Vesta is quite small.

Now Y/n is ready to watch the Rating Game with girls surrounding
