Over time, Gin's fondness for cross-dressing and looking cute allows him to meet others who are harboring their own secrets.

In order to find their teacher who had suddenly disappeared, Yotsuki and Kotowari went on a journey, visiting six of her friends as she instructed them to.

Blessed with the gift of magic, with the search as their goal, the girls' incident-filled fantasy story begins.

It's cute, whimsical, and so damn pretty.

Yuzuki is a call girl - a sex worker who doesn’t make prostitution her main profession. She gets sent to another world, and in order to get back to her own world she has to collect orgasms from all the different fantasy races that exist in the world she was sent to.

So yeah. It’s similar to JK Haru is a Sex Worker in Another World, but compared to that the fanservice is more explicit and the story itself less dark.

A 30 year old man named Koganei, Manato is down on his luck. He can't seem to get a job, has little money, is still a virgin and is giving up on his dream. Sitting alone on a swan boat in a pond next to a shrine, he holds a lottery ticket thinking this is the only way his dream may come true.

Manato ends up going back to the pond and after the mermaid decided not to kill him since he gave her food, she tells him about her dream to become human and how she wants to find love (she collects coins and throws them to a shrine in order for her wish to come true). Manato decides he doesn't want to get involved anymore because he has his own worries, but after another bad day he goes back to the pond. She finds him again and after listening to his complaints, she decides to give him all her saved up coins in order for his wish to come true. She suddenly turns into bubbles and disappears.

Confused and upset, Manato hears a strange voice and a god from the shrine comes to say that she will take the coins and grant him a wish. He decides to use his wish to bring back the mermaid as a human. His wish comes true and he sees the mermaid back as a human, but she's a guy! What will happen in this crazy love comedy!?
