Aren showed up to high school trying to turn over a new leaf after a rough delinquent past. He genuinely wanted to be a decent person and fit in, but old habits die hard—he'd occasionally slip back into his aggressive ways, which made Saiki nervous about whether Aren would actually cause problems at school.
On day one, Aren attempted to befriend Saiki and got hit with the infamous "You're Annoying" face. Most people would've backed off, but Aren noticed something interesting: everyone else flocked to Saiki anyway, despite that same rejection. So naturally, he decided he had to befriend Saiki too.
Underneath the tough exterior, Aren's got genuine loyalty and a real instinct to protect people. He's used his intimidating physique—a remnant of his delinquent days—to shield classmates from local bullies, proving he's not just about violence. He actually cares. Fans often note this contrast between his threatening appearance and his unexpectedly solid moral compass.
As a bit of trivia: his name is an anagram of "clairvoyance."
