Previously on Presence of the Supreme Omni God,

Y/n - Alright. I'll show that to you when we arrived at home. Irina, you want to come with us? You said while offering your hand to Irina.

Irina - Ummm.... Uh.... I don't know. She said confused.

In all of a sudden, Archangel Michael appeared behind Irina.

Archangel Michael - It's fine, Irina. You're free to go with Y/n. After all, you deserve freedom.

Irina - Archangel Michael?! She said while she turned around behind her.

Archangel Michael just smiled on Irina and Irina said,

Irina - Thank you so much, Archangel Michael. She said happily.

Archangel Michael - Your welcome. Now go, everyone is waiting for you.

Irina - Right. Thanks again, Archangel Michael.

With that, Irina went to Y/n and co.

Archangel Michael - Take care, Irina.

After he said that Archangel Michael ascended to heaven.

Now

Setting: At Y/n's house

Irina then looked at your house and she was pretty amazed by it because of how big and how beautiful it is.

Irina - Wow, you sure are have a mansion here, Y/n. I mean look at it, it's big and at the same time it's has a nice view from here.

Y/n - Gee, thanks Irina. I appreciate your comment.

Irina - By the way, how did you bought this kind of house or should I say mansion? And look, there is a swimming pool over there. She pointed the balcony.

Y/n - Oh, I didn't buy it. I created it using my magical powers.

Issei - Eh....

Irina - Eh....

Everyone (except Y/n) - Eh?!?!?!?!?!? They yelled in shock.

Issei - Did I hear that right?

Y/n - Yup.

Rias - You mean you created this kind of mansion all by yourself?!

Y/n - Yeah. Since I got here not too long ago, I created that mansion by myself. Anyways, let's go inside.

When you opened the main door, Irina was in absolute shock on how beautiful the inner section of your mansion.

Irina - Wow! She said amazed at the sight of the inner section of your mansion.

Y/n - Since it is only 11:00 a.m. I'm going to show to everyone one of you what is Super Saiyan 4 and teach Issei the Invisible Eye Blast technique. Let's go to the balcony.

Everyone (except Y/n) - Right.

As they put their bags on the couch, they proceed to the balcony.

At the Balcony

When the gang arrived, Rias and the others take a seat on the bench while Kiba standing there besides them.

Y/n - Now that everyone is ready, let's go Issei.

Issei - Right away.

You then clenches your fists and you instantly went to Super Saiyan 4.

Everyone is amazed on your form and Issei said with gleam on his eyes,

Issei - Amazing! That form looks so cool!

Irina - And you have a tail too.

Y/n - Yup. I always have. Unfortunately. I can't teach Issei to go Super Saiyan 4. But I can teach you how to master Super Saiyan 3 and teach you how to transform to Super Saiyan God.

Issei - Why?

Y/n - Because you don't have a tail like I have.

Issei - Aww.. That's sucks. But what did you say earlier? You can teach me how to master Super Saiyan 3?

Y/n - Yeah. Plus I will teach you how to transform Super Saiyan God.

Issei - Super Saiyan God?

Y/n - Yes and I will show you those forms.

You then reverted back to your base form.

Y/n - Your going to love this. Trust me.

Issei - Okay.

Y/n - What you are seeing now is my normal state or my base form.

You then transforms to Super Saiyan.

Y/n - This is a Super Saiyan. The form you saw during my fight with Sairaorg.

Irina - Uh-huh.

You then transforms to Super Saiyan 3.

Y/n - And this, this is Super Saiyan 3.

Irina - Whoa, your hair, it becomes longer.

Issei - So that is Super Saiyan 3. I think I have done that before but I can't remember how I did that.

Y/n - That's right. It is when you went berserk after what I have done Koneko and but she keep the act and you know the rest.

Issei - Ah! That's right! I now remember! Thanks, Y/n.

Y/n - Your welcome.

Issei then clenches his fists and started to transform to Super Saiyan 3. While doing that, the ground started to shake vigorously and Issei started to yell at the top of his lungs.

Irina - I-Impossible! How can he generate so much power?! She said in complete shock.

After a minute of yelling and powering up, Issei managed to transform to Super Saiyan 3 and the ground stops shaking.

Super Saiyan 3 Y/n - So you managed to transform to Super Saiyan 3. That's good. What we need to do is to master that form.

But before Issei can move, his Super Saiyan 3 form disappeared and he transformed back to Super Saiyan.

Super Saiyan Issei - Damnit, I can't sustain that form any longer.

You then reverted back to your base form.

Y/n - That's okay. That's why I will train you in order to achieve that form. Now let's go.

Super Saiyan Issei - Okay.

Y/n - That's the spirit. Now attack me with everything you got.

Super Saiyan Issei - Alright. Here I come, Y/n!

Super Saiyan Issei then attacked Y/n with immense amount of punches and kicks in which you only blocked them with your right index finger.

Once again, Irina is amazed on how you blocked the incoming attacks and she said,

Irina - I'm really amazed on how Y/n block those attacks. He blocks the attack so fast that I cannot see his finger moving. Just like he did with the battle with Sairaorg a while ago.

Rossweisse - You can say that again.

Y/n - Oh yeah, I remember!

Super Saiyan Issei - What did you remember?

Y/n - To achieve Super Saiyan 3, you need to master your Super Saiyan 2 first and then you need an immense amount of rage. Let's try that.

Super Saiyan Issei - Okay. He said as he backed away from you.

Y/n - Transform first to Super Saiyan 2, Issei.

Issei then transformed to Super Saiyan 2 in instant. Due to his sparring with Y/n few days ago, he successfully mastered Super Saiyan 2.

Y/n - Now do it, Issei. Be angry. Remember all the frustrating memories you got. That way, you can go further beyond.

Super Saiyan Issei 2 - I'll try.

Issei then clenches his fists and tried to remember all the frustrating memories he had. As he tried to remember those memories, a vein popped on his head and to his arms and began to start yelling at the top of his lungs while everyone is watching.

Once again, the ground started to shake vigorously and cracks are forming on the ground. As Super Saiyan Issei 2 let out a deafening yell, he sends a massive shockwave that knocked everything on his path while the others are watching with their eyes widen and Rias said,

Rias - His power.... is skyrocketing....

Irina - Yeah.... I can feel it too..

You then smiled as you know Issei is making progress. While Issei is yelling, veins are now popping all around on his body, his muscles is growing bigger, his power is rising exponentially, his hair growing longer and finally he emits bioelectricity that is cackling around on his body.

Y/n - Good. Very good Issei, you now successfully transformed into Super Saiyan 3. Now let's see if you can sustain that form longer than before.

Super Saiyan 3 Issei then rushed at you at blinding speed. So fast that he teleported behind you and performs a leg sweep kick in which you jumped and fired a ki blast. Super Saiyan 3 Issei swat the blast away just like an insect and to counter Y/n, he fired an immense amount of ki blasts in which you are deflecting away from you like it was nothing.

Irina - Wow, they're fast.

While deflecting the incoming blasts, Super Saiyan 3 Issei teleported you and fired an attack that Vegeta taught him.

Super Saiyan 3 Issei - Take this, Galick Gun!

Super Saiyan 3 Issei then fired a purple beam of energy from his hands.

You then quickly turned around and saw a beam of energy coming at you. You then move your in front of you and the beam stops in its way. After firing his attack, Super Saiyan 3 Issei, once again teleported above you and kicked your head but before his kick hit your face, you instinctively dodged the kick by leaning and that makes Super Saiyan 3 Issei a bit angry.

Once you tried to punch Super Saiyan 3 Issei, he only teleported and fired a close range ki blasts.

Y/n - I'm impressed Issei, you are improving and evolving as our fight continues and you are gaining full control on that form. I'm proud of you. You said as you block the ki blast with a glare.

Super Saiyan 3 Issei then backed away from you and said,

Super Saiyan 3 Issei - Thanks Y/n.

Y/n - Next will be meditation. Now let's go down and meditate a bit.

Super Saiyan 3 Issei - Alright.

You and Super Saiyan 3 Issei descended down to the ground and did an angel sit position and began meditating.

While meditating, the girls and Kiba joined them and began meditating well except for Irina.

Irina - Do you meditate every time when Y/n and Issei trains?

Rias - Yes. It helps us to heighten our senses and instinct when it is needed. Why don't you join us? I'm sure this will help you a lot.

Irina - Okay.

Irina then joined them and began meditating. While they are meditating, they were enveloped by blue aura.

After 30 minutes of meditating, all of them stood up and Irina felt different.

Irina - I feel that my senses were improved. Meditation sure packs an immense amount of benefits.

Rias - See? I told you.

Y/n - Next is I will teach Issei how to use Invisible Eye Blast. This training will be tough so get ready, Issei.

Issei then reverted back to his normal form.

Issei - Okay.

Y/n - First is you need to put and concentrate your ki to your eyes to activate the technique.

Issei - I'll try.

Issei then closes his eyes and focuses himself and decided to put his ki to his eyes. Once he opened his eyes, it becomes color red.

Y/n - Good now try to repel my blast.

You then fired a small ki blast and when the blast is at 5 inches apart from Issei, he successfully repel the blast and the ki blast disappeared.

Y/n - Very good Issei. Now I will add more ki blasts and don't worry, these blasts will deal minimal damage.

You then fired 3 small ki blasts and Issei began to stare intently to the incoming blasts. Once again when the blasts is near to him, a small shockwave was produced and he deflected the blasts with double of its power.

Y/n - Excellent job Issei! Now only you repel the blast and you returned back it to me with double of its power. You said amazed.

Issei - I did?

Y/n - Yup. You then placed your hand in front of you and absorbs the blasts, increasing your power permanently by 0.003%

Issei - Does that mean I successfully mastered the technique?

Y/n - Not yet. But I will teach how to master it. For the next round, I will add more velocity on my blasts and you try repel it okay?

Issei - You got it.

Issei then put and concentrate his ki to his eyes and when he opens it, his eyes became color yellow.

You then fired a small but fast ki blast to Issei and when Issei tried to repel the blast, the blast hit his face leaving a small explosion and minimal injuries.

Y/n - Are you okay, Issei?

Issei - I'm fine.

Y/n - Let's continue.

You then fired another small but fast ki blast to Issei but this time he managed to repel the blast but he didn't reflect it.

Rias - I have to admit but Issei is making progress here. I'm proud of him. She said while smiling.

Asia - Same here.

Y/n - Would you like to take break, Issei?

Issei - No, I can keep going.

Y/n - Very well.

This time, you then fired him a small but harmless death beam to him and Issei failed to repel the beam because it was too fast for him and it causes a small explosion on his face.

Koneko - I think Issei need to take a break otherwise  his face will become full of injuries. She said worriedly.

When the smoke is gone, you saw Issei is barely standing up.

Y/n - Alright, we will take a break first Issei.

Issei - O-Okay.

Asia - Do you want me to heal you, Issei-san?

Issei - Yes, Asia.

Issei then sat down in front of Asia and she began to heal him.

While Asia is healing Issei, you then went to the girls and you said,

Y/n - Does anyone else want to train with me?

Kiba then raises his hand.

Kiba - I do.

Y/n - Let's go Kiba.

Kiba then faced Y/n and he wields the sword of betrayal while you summons a yellow Ki blade on your right hand.

Kiba - Here I come, Y/n!

Y/n - Bring it.

Kiba then rushed to Y/n at full speed, attempting to slash him with his sword.
