Ep. 10: Hikari seeks to stop the freezing saltflake snow by performing the Ofunehiki ritual.
Aired on December 5, 2013
Uroko reveals that the Sea God’s weakening power causes saltflake snow to cool the world, potentially freezing all surface humans until his strength returns. To survive, underwater residents will hibernate, while villagers hold a Friday banquet before fasting. Believing the Ofunehiki ritual can appease the deity and avert disaster, Hikari persuades Uroko to allow him and his friends to attend school until hibernation begins, prompting them to review their preparations. During the banquet, Manaka is distressed by the situation and makes a wish after finding a sea slug with a red belly. The following day, Kaname confesses his feelings to Chisaki.
