Ryuuguuchou wa Umi no Soko
Ryugu Town is at the Bottom of the Sea·龍宮町は海の底
A small town exists beneath the ocean, otherwise similar to any land-based town except for being underwater. Two classmates, Masora and Sumire, are typical middle school girls who share personal stories and spend time together at local malls. Despite the normalcy of their lives, Sumire senses an impending disruption to this peaceful routine.
