A few days have gone by since your first day at Kuoh academy, you haven't gone back since as you had been doing your usual thing at the little space that you recently decided to call your new home

Kai was having a conversation with Ophis, you told them to talk to one another for once since the three of you were in a team, they at least should know one another

Ophis: So you really went and took on Rias and her gaggle by yourself?

Kai: Yeah...to be honest, I don't like Devils, they made my life hell when I was a child, so when they approached me...

Flashback

Kai was walking through a little section of the city when he heard some faint foot steps nearby, he looked over to see Rias and her peerage standing there

Kai, sensing their energy, realized that they were all reincarnated Devils with the exception of Rias herself, this put him off as he began to emit lightning all over his body

Kai: Devils...

Kiba; Fallen...

Flashback End

Kai: If Y/N hadn't put an end to our fight, I probably would of killed them all...I've trained all my life to get this strong, and then Y/N came along and he was so much stronger than me!

Ophis then looked to you with a smile before looking back to Kai

Ophis: Yes, he's really incredible...

You suddenly opened your eyes and stopped meditating, sensing a powerful energy nearby, it wasn't as powerful as you, but it was noticeable, it was even stronger than Kai

Kai: Is something Wrong, Y/N?

Y/N: I wouldn't necessarily say "Wrong", but I sense a powerful energy within the next 25 kilometres...Along with a bunch of small little ones, Devils...Stay here, I'll be back in a flash...

With that you suddenly vanished into thin air without saying another word, leaving Kai and Ophis to continue talking to one another

Meanwhile

In a little area in the city, just below a large bridge, was Sona and her peerage minus her newest recruit Saji, who was away doing other things for the benefit of team

Tsubaki went flying back and skidded across the ground, stopping at Sona's feet leaving her shocked

Sona: How could this be?! Just who are you?!

The mysterious figure emerged from the shadows to reveal a boy in what seemed to look like a wizards outfit, along with quite the weapon in hand

???: Who or what I am is none of your concern, I'm here looking for the one they call Kai...

Sona: Kai? The only Kai I know is the one that enrolled at Kuoh a few days ago...unless...Rias told me about someone named Kai that had them on the run...

???: Not going to answer? Fine, You can just perish with the rest of the city...

The mysterious boy suddenly pointed his staff at Sona and the rest of her peerage, all of them wide eyed and unable to do anything, a large orb of purple energy forming at the tip of the staff

???: At least the civilized proportion of the Devils can accept their fate...Now Disappear...

The boy then fired a large blast at the group of dumbfounded Devils as the blast tore through everything in it's path

Sona closed her eyes with a sad smile, accepting her fate when she suddenly heard a footstep in front of her, she looked and saw a certain figure that was you, standing in front of her as the Ki blast only got closer

The Ki blast collided with you and left behind a large explosion, the mysterious boy lowered his staff as the smoke cleared to reveal you in your true and most powerful form

Y/N: I'm not sure who you are, but you can't just go around destroying what I created...unless you're Zeno...which you are definitely not...

Sona: No way...!

???: And just who are you...?

Y/N: I could ask you the same thing, I don't know who you are, but I don't appreciate you going around and picking fights with my creations...

Tsubaki: "His" Creations...?

The mysterious boy pointed his staff towards you before firing a volley of purple Ki blasts, you began to deflect each and every blast with one hand without any effort as you inspected the Ki blasts

Y/N: He's definitely stronger than Kai...

???: Interesting...you wouldn't happen to know where I could find someone named "Kai" would you?

Y/N: And why are you looking for him?

???: He ran away from us, and I'm here to take him back...

Y/N: I see...well if that's the case, he must've ran away for a reason...he's not going anywhere with you...

The mysterious boy suddenly aimed another large Ki blast at you with the intent of destroying you

???: I'll make you talk...

The boy was about to fire the blast when you suddenly rushed towards him as time seemed to slow down, landing a devastating Kick to his face before he could even react to your movement

This one kick was enough to send him zooming far out of the city and crashing somewhere to the west, you landed in your feet and faced Sona

Y/N: Well, I guess that's that...

You were about to walk away when Sona called out to you

Sona: W-Wait!

Y/N: Hm...?

Sona: Could you be...Y/N...as in Y/N the creator of all...?

Y/N: If that's the legend you all speak of, them yes...

Sona: Wow...well...Thank you...

You stayed silent and smiled before turning around and waving

Y/N: You're welcome.

With that you disappeared into thin air again, heading back to your home

Y/N: I wonder who that was, he seems familiar with Kai, Maybe I could befriend him...
