Two weeks in Shibuya, he became friends with the Niijima sisters. Sae always babysat her sister and Akira, when Akira's parents and Sae's and Makoto's father had a lot of time at work, but she was fine with it. Makoto was very adventurous and dragged Akira mostly everywhere she could think of. Whereas Akira was a bit shy and reluctant, but Makoto was more outgoing, chivalric, bold and very stubborn. Sae had difficulties to tame her sister and sometimes it was tempting to rip her hair out, if they caused trouble. Mr. Nijima and Sae were informed about Akira's bad childhood and they were angry and saddened, what had happened to him. Sae cooked very small treats for Akira and gave him every few hours always something to eat. Her sister, Makoto, asked, why Akira was receiving something to eat every few hours. Sae answered her in a very slow way that Akira had a bad childhood, and so wasn't able to digest larger meals. Her sister had teared out, because even though she never experienced abuse, Makoto had always listened the stories from their father, how many parents he had arrested, who had abused their own children and what they did to them. After a few minutes, she composed herself and promised that she would protect Akira from harm, the same promise her sister had done, when she and her father learned the first time about Akira's past home life.
