Atsumu Miya is a 20 year old male and is the older brother of Ellie and twin brother to Osamu. He’s basically the opposite of Osamu. He’s immature, caring, funny. He can be quite condescending, and somewhat selfish at times. He also appears to be a perfectionist who has ridiculously high standards for himself and others, especially his own family. He’s protective of his siblings though and has a really strong bond with them. He has a soft spot for them as well.
