When you’re in pain, when you’re frustrated– you don’t need to be angry, all by yourself.

Sogo Osaka

Sogo Osaka (逢坂 壮五, Ousaka Sougo) is a very calm and soothing, if sometimes unsure, presence most of the time. He’s very reserved, though, and prioritizes being polite and following the order of things over what he himself may desire. However, he does have a switch, and if you press it Sogo very quickly turns into one of the most menacing members of IDOLiSH7.

Having grown up in a household that seemed to value pecking order and absolutes, Sogo doesn’t often let his own desires be known to others and represses how he feels for fear of otherwise causing trouble for the other members. A lot of these repressions–especially something akin to a fear of being abandoned, which may be a result of his uncle passing away. Sogo is also very aware of the ages of the group–he has held his age over Tamaki previously, and also very regularly goes to the older members for advice.

He's a self-described fanboy (particular of TRIGGER's Ryunosuke Tsunashi); played guitar in a friend’s band; dropped out of university; a very clingy, emotional drunk; former heir to a very large and influential company; prefers his food so spicy it hurts; holds very strong feelings of respect for his deceased uncle, who spurred his desire to pursue music.
