[You and Sugawara are siblings]
You are Sugawara's sibling. The most mysterious because you like to be alone, don't smile, always have a straight face towards someone, but Sugawara knows that you do all that just to forget all your fears. Sugawara just always accompanies you, tries to make you laugh and so on. You have a beautiful face even though you are a boy and Sugawara really hates it when people he doesn't know touch you
(Additionally you are a popular skating person with a mask)
You were looking for Sugawara because he left his training clothes in your class. When you entered the gym
Sugawara:"WHERE IS MY TRAINING CLOTHES!?!"
Daichi: "Suga-Calm down first"
Asahi:"Sugawara! Calm down first"
you saw Sugawara who was panicking trying to find his clothes while Daichi, Asahi tried to calm him down, Hinata, Kageyama, Tsukishima, Nishinoya, Tanaka, Yamaguchi, Ennoshita, Kinoshita, Narita, just remained silent in confusion, their two managers Kiyoko and Yachi just watched even though Yachi was also panicking. The gym is just filled with the sound of Sugawara screaming, panicking because his training clothes aren't there until you do something that makes him fall silent
