Gama Gama Aquarium, a small aquarium in Okinawa, is an hour's bus ride from Naha. Kukuru Misakino is an 18-year-old high school student who works there, and she knows about the "secret" of the aquarium: sometimes you can see mysterious things. One day Kukuru meets Fuuka, standing in front of a water tank with flowing hair and a tear rolling down her cheek. Fuuka has given up on her dream of becoming an idol and she has run away from Tokyo to Okinawa. Wanting to find a place to belong, Fuuka earnestly asks to work at the aquarium. The manga follows Kukuru and Fuuka as they deal with the issues of the secret of the aquarium and a looming crisis of its possible closure.

When I noticed it, I was transferred to the fucking social game "Abyss Calling", which is said to be the worst collection system. Stand up as a summoner in a new world to accomplish what you left behind when you were a player!

Aizawa Haruki, 16 years old, is in his 2nd year of high school and likes to live efficiently. One day during summer vacation, a girl, Aizawa Himari, suddenly appears, calling him 'Onii-chan' and claiming that she's his little sister. As it turns out, Haruki's father recently remarried, and his new wife brought a daughter with her. However, since both of their parents are overseas, it'll only be the two of them living under the same roof. And for some reason, Himari seems very obstinate about spending as much time with Haruki as she can.
