(I will relate Kiba's tragic past on the anime because I can't think anything else. So yeah, there you have it.)

Previously on Presence of the Supreme Omni God,

Y/n - How about you, Issei, what is your dream?

Issei - Right. Before I became a Saiyan, my dream is to become a Harem King. In case you didn't know, A Harem King is a person that all of the girls are attracted to you. Something like that.

Y/n - Uh-huh.

Issei - But now, when you turn me into a Pure blooded Saiyan, I've changed. I don't know why I've changed but it doesn't matter to me. Now, my dream is to become the strongest being on this universe. He explained.

Y/n - We have same dream when I was little, Issei.

Issei - What do you mean?

Y/n - Back then I wanted to be strongest being in the whole multiverse so I fought countless enemies and to become stronger and stronger that eventually I successfully beat the previous Omni God which is Zeno-sama and you know the rest.

Issei - Yeah. I know.

Y/n then looked at the clock and it says that it is 9:30 p.m.

Y/n - It's getting late. We should go to bed now.

Issei - Right.

With that you and Issei went to their respective bedroom and everybody now in the mansion is now fast asleep.

Now

The next day and morning appeared as Y/n doing his usual workout while Issei just woke up and noticed that Y/n's bedroom is empty. He then knocked at the door which it belongs to Rias. He knocked three times and waited it to open. After a while, the door open, revealing Rias on her bedroom attire.

Issei - Morning, Rias-senpai, did you know where is Y/n?

Rias then think first then she said,

Rias - I think he is on the balcony doing his usual morning workout.

Issei - Thanks Rias-senpai. He said while smiling.

As Rias saw that heartwarming smile, her heart suddenly skipped a beat and her face became suddenly red just like his crimson red hair. Issei notice her that she is acting weird and he said,

Issei - Uhh......Rias-senpai, are you alright?

Rias - Uh.... yeah, yeah. I'm alright.

Issei - Okay. I should find Y/n right now.

Rias - Yeah, you should find him now.

Issei - Well, I'm off now.

With that, Issei take his leave while Rias's face is still red.

Rias's mind - 'Why did my face became color red? Why did my heart beats faster? Just like at Y/n, I fell in love with him at first sight and to Issei too?? I can't choose who will be my boyfriend. Is it Issei or Y/n? I'm so confused but I will let it be until the right time.'

Timeskip brought to you by Chibi Issei, searching Y/n.

After 5 minutes of searching, Issei finally found Y/n doing a one-arm push ups.

Issei -  Oh there you are Y/n. I've been looking for you for 5 minutes. What are you doing right now?

Y/n - Doing my morning workout to become physically healthy.

Issei - I see.

You then finishes your workout and you drank water. After a while, you asked Issei,

Y/n - Ready for our training?

Issei - You bet.

You and Issei then turned to Super Saiyan and beagn sparring to each other.

Inside the Mansion,

Kiba then felt the intense energy of Issei and Y/n and he decided to look for them. When he reached the balcony, he saw Y/n and Issei, sparring to each other.

Kiba - Oh there you are, Y/n.

You then looked down and you and Issei saw Kiba,

Issei - Kiba! What brings you here?

Kiba - Well, I'm here to talk about my past and I need both of your assistance to overcome my past.

Y/n then went back to his base form as well as Issei. You seemed to be interested on helping Kiba and you and Issei descended down on the balcony.

Y/n - So, what did you want to talk about? About your past and you need our help to overcome it?

Kiba - Yes.

Y/n - Count me in!

Issei - Yeah me too!

Kiba - Thanks, guys. Now to begin, do you know the Holy Sword Project?

Y/n - You mean the project that failed?

Kiba - Yes and I am the only who survived. Sadly to say that my comrades were dead during the project. When they said to run away, I was hesitant at first and eventually I ran away because I don't know what to do to help them. I ran away as far as I could until someone saw me. That person saw me was the President, Rias Gremory.

Issei - Eh?! You saw the president?

Kiba - Yeah. Through her ritual, I've become a devil. I was once a human when the project failed. Now I want to destroy the Excalibur and to avenge my comrades.

Y/n - And who is the one you will defeat or should I say, kill?

Kiba - Kokabiel. All 7 holy swords are in the hands of that bastard and I want to kill him and proclaim my to objectives and they are: to destroy the 7 holy swords and to avenge my comrades before.

Y/n - Sounds that you have a tragic past there, Kiba.

Kiba - I know and I need your help to defeat him because in my state right now, I can't defeat him so I need your training just like Issei.

Y/n - Sounds interesting. Okay, I will help because I love helping people.

Issei - Yeah me too. I don't want my friends struggling on their personal problems and I want to help them just like Y/n.

Kiba - Thank you so much guys, Y/n let's begin our training as soon as possible.

Y/n - Right away.

With that, Kiba then summon a sword from his hand and both of you faced each other to began Kiba's training and Issei went to the bench, watching them.

To be continued...
