Re-Main

 

Re-Main is a really good anime I just recently for into because of a friend. It is very interesting. The main character is really good a water polo and is ranked one of the best in the nation. Then a terrible accident happened and he forgot everything about water polo. He gets his memory back day by day and gets more confused, and more mad about it. One day he finds his family talking about how they want his old self back. Getting mad he storms up to his room where he found an old video of him before the crash. He decides that he will start doing water polo again. This is a really good anime! 

Can watch it on Crunchyroll
