Stream Anime Free! – Iwatobi Swim Club Episode 4 Online English dub Captive Butterfly! The Swim Club officially starts training in the refurbished pool using an old training regiment of Rin’s Gō had unearthed. Rei’s inherent academic skills at learning all the swimming theory prove to be useless since his body refuses to move in the water. Elsewhere, Rin grudgingly realizes that his victory against Haruka was due to Haruka’s lack of physical training and not his actual talent. Nagisa and Makoto start teaching Rei how to swim and learn that while he can float, his problem still eludes them. The following day, the guys try to come up with designs for a club uniform but Gō instead gives Rei’s lessons higher priority and makes a revamped swimming regiment during which he must master swimming in one week before their first prefectural tournament. Nagisa and Makoto try and fail to teach Rei their signature techniques; the breaststroke and backstroke respectively causing Rei to blame his inability on their teaching methods.
