Sigma Is a Cosplayer

Sigma is a well-known cosplayer, especially fond of obscure characters. So among all the Osamu Dazai cosplayers, his Sigma stands out like a crane among chickens. And so he is chosen by the will of the world. And so he transmigrates. A frail young man with two-toned hair stands dumbfounded in the cold wind and can't help shivering. What gives? Are obscure characters not even allowed to be cosplayed these days?! I object!!! Theme: Everyone has a responsibility to care for obscure characters
