The book Ren brought from Canada is one of Haru's old favorites and a story about a lone gray wolf who meets a human he comes to recognize as his master. Already hating himself for making Ren say he'll be "just a brother," Haru is dealt the final blow by Seika's words. Meanwhile, Ren manages his school life with the help of his classmate Juuzen and Kondo Kiri, another student returned from abroad, but he collapses during a PE class...

 apenas um irmão mais novo,
