Shizuru Isurugi (石動 静流 Isurugi Shizuru) is one of the minor characters in Free!'s third season, Free!-Dive to the Future-. He is a 1st year high school student at Iwatobi High School and a new member of the Iwatobi High School Swim Club under Rei Ryugazaki's captaincy.


Shizuru is a taller than average young man with dark brown hair, blue eyes and a somewhat dour expression at all times. During training, he wears the usual uniform of the Iwatobi swimming club.




Shizuru first appears when Nagisa wants to take photos of the new club members in order to send them to Makoto. Later, Shizuru can be seen practicing at Iwatobi SC Returns where Iwatobi's team begins preparations for Nationals. He expresses great interest in the camel that appears in the promotional video for the Iwatobi High School's swimming club. He is the one who discovers the guide from Gou's island training camp from years ago.




  • He apparently suffers from severe motion sickness, to the point of passing out.[1]
  • His family owns a seafood shop and the seaweed gathered by diving is why Shizuru is good at swimming.
