Kyoichiro confronts the elderly man, revealed to be Momo, the siblings' father. Meanwhile, Mutsumi transfuses her blood into the weakening Taiyo so the Someinine from her heart can heal him. Yama nearly grabs Mutsumi but Taiyo awakens with the Yozakura crest in his right eye. With the Someinine, Taiyo begins to develop Yozakura superpowers but struggles with the stress on his brain. Mutsumi helps him focus until Yama pushes her aside. Enraged, Taiyo kills Yama with a single punch. Kyoichiro deduces Momo manipulated the situation so Mutsumi would give Taiyo Yozakura-style abilities. Momo admits he did so to ensure Mutsumi had a husband who could protect her. With this achieved, he turns to leave but Kyoichiro attempts to kill him with an attack so powerful his Steel Spider cut down the forest. Elsewhere, the siblings clear out Tanpopo's army. Momo survives Kyoichiro's attack due to his even greater mastery of Steel Spider and escapes, though Kyoichiro does retrieve Momo's ring. Taiyo goes berserk from Someinine Hyperactivity, a common ailment among Yozakura infants, so Kyoichiro pacifies him with Mutsumi singing directly into Taiyo's ears. Futaba is surprised Kyoichiro chose such a gentle method, which Kyoichiro denies.
