Sei

Sei is often described as "feeble". He is very pale, almost sickly-looking, highly possible due to the constant years of experimenting on his physical and mental being. He adorns long, dark blue hair that reaches down to his neck and black eyes. His build is very slender, but looks to be more broader compared to Aoba's. Despite being twins, Sei's gloomy appearance causes him to look drastically different from his brother, who dresses and looks more lively in comparison.

Sei's outfit consists of a studded, black fedora with a Morphine pin on the side. He wears an open shouldered, long sleeved white shirt that has black straps over his shoulders. He has matching jeans and gloves that have skeletal designs and wears a half skirt that is connected to the right side hem of the pants, connected by black suspenders that hang on either side of his body. Two studded collars adorn both his neck and wrists. He also wears a pair of white boots with black studs.

Sei is also noted for his very androgynous appearance, by both players and even Aoba himself. When Aoba first sees one of Sei's images in an alleyway, he refers to him with the gender-neutral pronouns "they" and "them", implying he could not tell if Sei was male or female at first glance. It was not until Toue's introduction of Sei did Aoba realize he was indeed male.

When first introduced, Sei seemingly has no interest in others. He acts very distant and has a very dead gaze in his eyes. However, it's revealed that the reason for his cold exterior is because of years of testing that has deteriorated his physical and mental being. It is not until Aoba is pulled into Sei's mind that the true Sei is shown to be a very kind and soft-spoken person. He's shown to care deeply for Aoba and Ren, his final action proving how much he wanted them to be happy. Despite being lifeless at first, Sei is almost always seen smiling, even during the destruction of Oval Tower.
