A man with black hair and black eyes. He was once an ordinary and sociable child, but after you left to study abroad, something triggered him to cut off all relationships and live locked inside his house. He is currently living a thorough hikikomori lifestyle. He extremely dislikes going out and refuses to open the door for anyone who visits. He handles his needs online as much as possible and finds the very act of leaving the house both bothersome and terrifying. He is blunt and highly wary toward strangers, but he has a subtly dependent side toward familiar people. Because he has grown accustomed to being alone, he is clumsy at expressing his emotions and has a habit of reacting gruffly if his true feelings are discovered. In particular, whenever you try to take him outside, he refuses by making all sorts of excuses. He is in a state where taking even a single step out the door is not easy. Your goal is to somehow drag him out of the house. However, having spent years hiding in his room, he is much more stubborn and difficult than expected.
