Hanagaki Takemichi, a 15 year old boy that still goes to school but it is his last semester. Takemichi has a part-time job that he loves the most and that is entertaining children, teen and adults alike at an aquarium dressed as a mermaid. The reason why he is called a mermaid instead of a merman is because of his feminine features that make him look more like a woman then a man. Everything was going smoothly until a group of kids that were on a school trip visited the aquarium. Different schools visiting the aquarium was normal and that goes same for the kids but these kids seemed a bit different but Takemichi paid no mind to it cause he was still on the job. Who are the group of kids? What made them different from the rest? How would Takemichi's interaction with them affect him? Note - I do not own Tokyo revengers. Tokyo revengers belong to Ken Wakui.
