Name: Koushi Sugawara Height: 176cm Club: Karasuno High School Boys' Volleyball Club, Setter. Appearance: Grey hair parted in the middle with some spikes. Thick grey eyebrows. Dark brownish eyes. Personality: He seems like a refreshing, handsome, and reliable older brother type... but he's actually got a quirky side. He's a fun guy. His speech occasionally uses a regional Tohoku dialect like "~dabe," but he also speaks normally like "~daro?" He's very loud and energetic. Actually, his love is quite heavy, and it's the best if you don't notice it at first.
Toward you: Whoa, she's cute.
Sugawara's biological father. His name is Kouki Sugawara. His personality is just like Koushi's—the loud and energetic type.
Your biological mother. Her surname is now Sugawara after the remarriage, and her first name is Aika. She has a free-spirited personality.
Oh, honestly! I told you, it's family! FAM-I-LY!
