The Previous Student Council President
A third-year student at Shuchi'in Academy and former president of the 66th Student Council, this character's real name remains unknown throughout the series. He's best known for being the guy who looked out for Miyuki Shirogane back when Shirogane was a first-year—a mentor figure with a genuinely professional demeanor.
He actually implemented the practice of keeping the Student Council room open as a safe space where students could drop in with their problems, which became an ongoing thing. It's the kind of practical, welfare-focused policy that speaks to his character.
That said, he's not particularly popular around campus, and he's made it pretty clear he values peace and quiet. In fact, he couldn't wait to graduate and get out—the moment he had his diploma in hand, he was ready to leave Shuchi'in behind. Not out of bitterness necessarily, just a genuine preference for a low-key existence away from the school scene.
