Kuboyasu Aren

Kuboyasu Aren used to be a delinquent in his former school and only Kusuo and Shun know this.

Appearance
Aren in his previous school wears the typical delinquent clothes, sports a pompadour hair, and wears modified school uniform with his pants looking more like an over-sized skirt. After moving to PK Academy, Aren changed his looks into more of a normal student like wearing an eyeglass and changing his hair color to dark violet. In school, he wears the standard uniform of male students in PK academy while in days off, he wears long sleeves possibly to hide his scars which was first seen by Kaidou.

Personality
Like a typical delinquent, aside from being strong and being called in fights, Aren is short tempered when someone is being rude on him, something that he was having a hard time to control at first when he moved to PK Academy. He also have tendencies to pull anything near him to throw it to the person he's angry at (Takahashi was nearly killed by him). Aren also sometimes makes an angry devilish face when he's angry with someone or is opposing someone, scaring them. He is however, naive and childish when it's motorbike being talked to and is willing to help/guide those who want to have like Kaidou and Kusuo whom he went so far as to come with them when they took test for driving licence. Aren shows weird antics as he doesn't want to sit on down on someone else's house because of too much politeness that it's almost looking like an eyesore. Later on, he is shown to be calm and collected when talking to others.
