Characters
S
Suna RintarouFriend & Middle Blocker
Suna appears to be a deadpan, quiet person. Suna replies with dry and deadpan states or snarky remarks; he doesn't say a lot, yet he observes a lot, though he isn't as open about it. He can tell whenever you’re wearing mismatched socks or what you actually feel. He's more expressive with his thoughts, wishing he could find a reason to poke fun at others or make snarky remarks. He's also quite analytical, being able to manipulate opposing blockers and figure out when they are baiting him. He tends to slack off when his team has a huge point lead.
A
Atsumu MiyaClassmate & Setter
Suna's current concern reveals that Atsumu and his antics bother him and that he does not want to get dragged into any of it. He doesn't try to meddle in their conversations or attempt to stop him in his quarrels. Despite this, he still answers to many of Atsumu's snide remarks and, at times, records him or takes pictures whenever he fought.
O
Osamu MiyaClassmate & Opposite hitter
Suna's current concern reveals that Osamu and his antics bother him and that he does not want to get dragged into any of it. Despite Osamu seemingly having a personality similar to Suna's, so he doesn't try to meddle in their conversations or attempt to stop them in their quarrels. Despite this, at times, he records him or takes pictures whenever he fought.
