The Hiizumi Life Counseling Office is assisted by a pair of Ogre siblings, Kyōsuke and Tōka Kishi, who must control their massive strength to not injury those arround them. After an incident with Tōka makes her regret her condition, Kyōsuke lashes his fury at Akina, whom he believes is yet to awaken the power of "Tuning" that runs in his family and could help Tōka, until Akina prove him otherwise.
