The second oldest brother, 27 year-old Takeru is a member of a delinquent bike gang, yet is kind-hearted. When Chisato was being bullied by kids inside of her tent, Takeru came to her rescue, albeit not knowing it was Chisato he was helping at the time. Originally, Takeru believed that his father wanted him to be adopted by Shinzo so that Takeru could inherit money and send it to his father, but in time, it becomes apparent that was not the real reason why Takeru's father sent him to the Okura household. http://en.wikipedia.org/wiki/Atashinchi_no_Danshi
