Third-year student and president of Jindai High's Student Council. He's basically the calm, rational type—never gets visibly angry, which actually makes him pretty effective at his job. He's known for carrying around a white fan with Japanese characters written on it, though the specific words change depending on the occasion.
The interesting thing about him is how he views Sousuke's constant chaos. While Kaname finds Sousuke's behavior totally unacceptable, Hayashimizu tends to see it as a reasonable (or at least understandable) response to whatever ridiculous situation Sousuke's gotten himself into. That's basically why he recruited Sousuke as the Student Council's security officer—he actually respects the guy, and the feeling's mutual. Fans often note that their dynamic works because they genuinely understand each other, even when everyone else is losing their minds.
