Hanzawa's the kind of senior who's hard to figure out at first glance. He comes across as friendly and laid-back, but there's something quietly mysterious about him—he doesn't reveal much, keeps his composure even when things get weird, and has this unsettling ability to pick up on small details about people and actually remember them. His motto is basically to smile every day, which sounds simple but apparently he actually lives by it.
Despite juggling two club commitments plus his dorm head duties in his second year, he's somehow always available when his juniors need him. That said, he's not above getting in some good-natured ribbing—he'll tease Kagiura about his obvious crush on Hirano, make comments about Miyano's height (or lack thereof), and mess with Tashiro. It's never cruel, just the kind of teasing that comes with being in his orbit. Fans often note that beneath the easy smile and casual demeanor, Hanzawa's probably more perceptive than he lets on, and that makes him both approachable and slightly unreadable in the best way.
