A Whale Shark's Ray (Free!)(SousukexOC)(Boyxboy)

Munto Takamuri has always had a strange pull towards water. He didn't like being dry, and would purposely dump water on his head just to release his anxiety. Needless to say, he was also a swimmer. And much like a certain well-known Haru Nanase, he swims freestyle.

But the two are very much different. Munto is far from appearing emotionless, but he is mysterious. His long-time friend Satoshi Kawa, who swims the backstroke, has often called him Manta, short for Manta Ray, after seeing him swim as a child.

Due to his grandparents' worries, Munto has been given a limited amount of time to get over his addiction to water.

But how can he do that when it's his only sanctuary against a world that frightens him?
