S2·E23 The Promise

The girls have Honoka join them for dinner, where they celebrate Kokona's birthday together. Later that night, Honoka gives some advice to Aoi concerning her promise, and the two exchange contact info with her. The next morning, as the girls continue their ascent, Aoi and Hinata look back on their recent adventures as they finally watch the sunrise together, realising that their promise will continue forever as they keep making memories together.
