He was angry with his sister's decision to marry a man who has two daughters from previous marriages. When Yuri and her husband, Shingo, go missing in a plane crash while on their honeymoon, their three daughters, 14 year old Sora, 10 year old Miu, and 3 year old Hina, had no one to turn to. Outraged by their relative's decision to split the 3 siblings apart, Yūta makes a decision to take them in and becomes their guardian despite what their family told him. He is surprisingly reliable. Even the youngest daughter of the three, Hina, quickly got close to him. He has feelings for Raika.
