قسمت 23: هیکاری در حالی که میونا و سایو اعترافات عاشقانه خود را مدیریت می‌کنند، با تسومو رو در رو می‌شود.

Still distraught with Uroko's revelations, Hikari is approached by Miuna who suggests him to confide what they just learned to the others, including Manaka, but he disagrees. After Miuna persuades him to at least reveal the truth to their friends, they gather them at Tsumugu's house. Kaname and Chisaki claim that Manaka's condition maybe could not be a bad thing at all, but Sayu lashes out at them for considering such thing. After their meeting, Sayu reveals to Miuna that she could only move on with her life thanks to her feelings for Kaname, unrequited or not, thus she could not agree at all with the idea of losing them. On their way back home, Hikari and Miuna meet Manaka and they find a white rock that according to them, is the same one produced by red-bellied seaslugs. Believing that the rock is a sign that Manaka's wish to the seaslug five years before was granted, Hikari gives it to her, although she can't remember what was her wish, and Hikari then realizes that such wish had something to do with her lost memories of love. In the next day, while making a pendant for Manaka using the rock, Miuna learns from Sayu that she intends to finally confess her feelings for Kaname. At the shore, certain that Manaka's feelings of love are for Tsumugu, Hikari asks him to hang out with her in order to have her lost memories and feelings return, but he refuses much to his anger, and when a passing by Chisaki watches Hikari attacking him because of it, she rushes to help. Tsumugu, efortlessly evading Hikari's attacks, reveals that he in fact loves Chisaki, who flees to the sea after hearing it, and when Tsumugu dives after her, his body also gains Ena just like Miuna's and the cursed fish at his arm swims out, guiding him to catch up to her at Shioshishio. In the occasion, Tsumugu reveals to Chisaki that he always liked her way before the day of the Ofunehiki five years earlier. (Source: Wikipedia)
