In the town in Kuoh, Japan and at the Hyoudou's residence where our protagonist is as we see him walking towards his little brother's door and he was knocking at the door and he said.
Y/n: Yo, Issei. Get up. We have to go.
He did hear him having a dream about girls, as he walked in and saw him with a smile in a perverted way. He sighed at him and proceeded to punch him in the gut causing Issei, his little brother and who's a pervert, wake up from his bed and look at his older brother, Y/n Hyoudou and our protagonist who has something special in him and he's older than Issei who hates perverts including Issei to only discipline him or punish him, who looks at Issei and told him to get ready for breakfast and head to school.
So, he went downstairs to go the kitchen and saw his parents, so both of them started to eat breakfast while talking to their parents and Miki said about Y/n's getting a girlfriend, and Y/n looks at his mom as he was blushes. So they're walking out the door and heading towards the school, Y/n looks at his little brother and said.
Y/n: Issei. You better not do anything stupid.
Issei: I won't. But you know that you like me as your bro, right?
Y/n: I know. Even though you're a pervert and a brother that doesn't mean that I hate you.
Issei saw his friends and did their handshake while Y/n walked past them and continued to the school called Kuoh Academy, an all girl school but now became Co-ed with the boys. Every female knows Y/n because he was their protector to the females and he was friends with Koneko Toujou, the school's mascot, and Kiba Yuuto, the school's prince. Koneko and Y/n have something in common, they love sweets and hates perverts.
Then later on the day and around outside to workout, while he was taking a break from his exercise and he sees Issei's two friends were running away this makes him confused as he was getting up and walked as he sees his little brother and kendo girls were about to punish him but he has to step in and said.
Y/n: Girls. What're you doing?
Kendo girl 3: This pervert is peeping in on us while we're changing.
Y/n looks at Issei with a "you're dead" look on his face, Issei made a paled face at Y/n as he was in fear because Y/n is known as the ultimate pervert hater and Y/n looked back the kendo girls and said.
Y/n: Girls, I apologize for my brother's actions and I shall punish him myself.

Katase: Promise?
Y/n: Yeah. Next time when he does it again and I will not show mercy.
He looks at Issei with a dark aura around Y/n and Issei was shaking in fear. So the kendo girls walked away from them. At the area near the club house where Y/n and Issei was sitting down, Issei looks at his brother and said to him.
Issei: Can't believe those jerks ran away from me.
Y/n: Good. Those guys are bad influence on you anyway. Also, Issei. When are going to stop being a pervert, man?
