On holidays and after school Issei trained to master all his abilities, in a secluded area. Ddraig also taught him how to use the boosted gear.
Sometime during his childhood, Issei met an old man who told him and other children stories about breasts, which eventually led to Issei's fascination with them.
He attended the same middle school with Matsuda and Motohama and the three of them started attending Kuoh Academy one year later.
The three of them became known as the perverted trio. They were caught multiple times for peeking at girls while they were changing. Well except for Issei. Everytime the girls cornered them Issei always mysteriously disappeared.
Some of the girls liked him for his looks and others hated him for his alleged peeping.
One day
While Issei was walking home.A girl walked up to him and confessed to him. She asked him for a date.Issei sensed that she had was not normal. Ddraig told him that she was a fallen angel.
"A date huh. Well I have been wanting to go to that new Café. I heard they got some tasty desserts" Issei thought
"What is with him and his obsession with sweets. The girl is merely afterthought to him." Ddraig thought
"Yeah sure let's go out. What's your name" Issei
"My name is Yuuma." Yuuma
"Let's meet at MgRonald's"Issei
''Ok" Yuuma
Next day
They go on their date.They meet up at MgRonald's After they finished eating at the restaurant they went to the Café. Yuuma was annoyed. Issei paid in no interest in her. He was only concerned with the food.
Time skip to park
Issei was sitting on the bench licking his ice cream.
Raynare had her back turned to him.
"This bastard how dare he ignore me. Why did he even go on this date if he wasn't even to going to make conversation with me." Yuuma thought angrily
Yuuma calms down.
"It's time to end this charade." Yuuma thought before she turned around.
"Issei would you do something for me "Yuuma said with a cutesy voice
Issei stops licking his ice cream.
"Yeah sure.What do you want me to do." Issei said
"Would you die for me" Yuuma
"I wonder what sweets I should buy tomorrow." Issei said as he ignored her request
"Did you hear what I just said!" Yuuma said irritated
"Kikufuku or maybe Daifuku." Issei
"You bastard" Yuuma said before she transformed

You should have worn that for our date then I would have given you more attention." Issei said
"You perverted bastard. " Yuuma said before creating a light spear
"Die" Yuuma said as she tried to stab him.
"Oh no I am going to die" Issei said dramatically
His Infinity blocked the spear.
"Why can't I hit him." Yuuma thought
She tried to stab him again and again. Issei was simply licking his ice cream while Yuuma was attempting to kill him.
She was getting frustrated.
She created a light whip. She tried to hit him again but failed.
"Damn it." Yuuma
"You human trash. How dare you treat me like I am insignificant." Yuuma thought as she saw him ignoring her.
Issei finally stood up. Yuuma got on guard and jumped away from him.
Issei walks away from her and starts to walk home.
Yuuma got pissed as she saw this.
"You bastard die." Yuuma before she created a ton of light weapons.
Issei turns around.
"At first if you don't succeed try again. You are taking that phrase to seriously. You have tried and tried again. Why don't we just called it a day and go our separate ways." Issei
"Just die already." Yuuma said before she firing all the weapons at him.

The light weapons exploded upon contact with Issei's Infinity.
When the smoke cleared up. Yuuma saw that Issei was gone.
"Where is he." Yuuma
"Behind you." Issei
She turned around only to blasted away by Issei.

Issei twisted apart her limbs and broke her neck using his Limitless.
Yuuma's dead body bursts into feathers.
"Stupid girl I gave her a chance to live." Issei
"Running from a human would have hurt her pride." Ddraig
"Idiot" Issei said before disappearing.
