Since this title does not match a widely known mainstream manga, anime, or game (it bears similarity to franchises like Mermaid Melody , Muromi-san , or gacha game events like Blue Archive’s “Mission Mermaiden” or Azur Lane’s shipgirls), I have constructed a based on the most logical inference: A Japanese mobile game / visual novel event featuring a character named Hasumi on an underwater mission.
