Episode Title:
Thing That Was Lost.
Episode Description:
Hikari and his friends start searching for Uroko-sama without success. Meanwhile, the temperature around the country continues to drop and the snow spreads further inland prompting Professor Mihashi to be called back to the university. Tsumugu decides to stay for a little more, claiming that he must continue their research, but later reveals to Kaname that his true intent is to stay near Chisaki. Meanwhile, Hikari realizes that Manaka has lost her memories from several situations they had experienced together, including the time when he confessed his feelings to her. Some time later, Hikari and Miuna finally meet Uroko-sama at a nearby shrine and he explains to them that Manaka had become an Ojoshi for the Sea God, and it helped delay the cooling of the planet. But when she was taken back to the surface the cooling began once again. He also reveals that just like Manaka, the original Ojoshi could not discard her feelings for the loved one she left behind and the Sea God allowed her to return, but it took away her ability to love, and any memories of love, instead. A desperate Hikari then realizes that at her current state, his feelings for Manaka will never reach her at all.
