Kagura Yoshiaki

He is a young man who looks exactly like the main character.

He is mild-mannered, intelligent, and has good grades. He seems to be out of the loop, but his instincts are sharp. He always has a smiling expression on his face, but the expression itself does not change much. His father, who was well-liked by everyone in the family and seemingly happy at home, burned himself to death, and he is practically the centre of the family.

His real mother is presumed to have disappeared. After meeting the protagonist again, he takes care of him in any way he can.
