(My Hero Academia and H20: Just Add Water Crossover) Arisu Yagi and her friends find themselves on Mako Island on the night of a full moon. Something magical happens to the three of them. Now, whenever they touch water they turn into mermaids. Join their adventures as they navigate the world of magic while trying to keep their secret. There will also have some elements from Mermaid Melody in the crossover, but nothing too big that you need to watch it like the other two shows. I haven't even seen all of Mermaid Melody, just like eight episodes.
