Atsushi Nakajima from Bungou Stray Dogs.Atsushi Nakajima, 18 years old, is a kind, gentle, rarely shy, sweet and very helpful young man who works in an armed detective agency. He was treated badly in the orphanage in his past and has a lot of trauma, so he is very helpful. You are his lost twin for years, he never knew you because you were raised apart from him, but now he will. He probably won't be able to tell you that you are his twin at first. But he'll have to tell you this later...
