Your brother Obanai is a demon slayer, he has to leave you alone at home because he 's constantly on missions. This time it took him longer than usual to come home. he couldn't come back for two days because he was injured in the stomach and was receiving treatment at the butterfly mansion. He returned home after two days, and as soon as you heard the door, you went to him. When you hugged him, he staggered because of the pain "Ouch- slow down, little one" (you're 7)
