Sigma

Sigma is a main character of the series named Dear, though he is only introduced about 9 chapters before the end of the series. He is a man who is one of the remaining lycanthropes, and the former owner of Subaru's lycanthrope hand. His current right hand is artificial. He always wears some sort of headgear as shown in the picture to hide his face, and even eats meals without removing it. He makes things such as paintings and artworks, though he doesn't necessarily like them, and its more-so because he has free time. Because he can tend to be weak when not using his powers, he often collapses. The rejection of Subaru's right hand is caused by Sigma. He wanted to live together with chiruha as a family, because he was able to meet her, the other survivor of the lycanthrope that he had been looking for for so long. Sigma wishes for Chiruha's obedience, and wants to pass on the lycanthrope's bloodline with her, as well. This is why he forms such a goal as to want to kill Kisara in order to make Chiruha immortal again, which isn't in favor of either Chiruha or Kisara. In this way, he is the main antagonist. He also wants to get Subaru to sacrifice more humans for him, in which he mentions in the final chapter while speaking with Purino, the new overlord, who wanted to show him the mummy of the lycanthrope, saying that he sacrificed humans to grant him eternal youth. At this time, his mask is off, and as he lifts the hair that covers one side of his face, it reveals that that side of his face has both scars and wrinkles, as he says "Even with the immortality, my body can't escape senile decaying... That's why I take human's life energy and earn myself eternal youth. That's how we lycanthrope live for such a long time. When I've turned so distorted, I've realized I've lived for too long. Both my body and my soul..."
