“Claims to be the world's best setter — and then backs it up with his hands. The loud one of the twins.”
Atsumu is the rare case where confidence and ability actually match. His self-promotion sounds like bragging until he goes and proves it in the rally. His ego is real — but so is his service ethic: getting the perfect set to every spiker is genuine, not a performance. The constant bickering with Osamu is just how the closest brothers communicate.
