Interference of Loss! (喪失のインターフェア！ Soushitsu no Intaafea) is the fourth episode of season three of the Free! anime and the twenty-ninth episode of the overall series. It aired on August 1, 2018.

Synopsis
Haruka Nanase, Makoto Tachibana and Asahi Shiina are waylaid by Hiyori Tono at Shimogami University and are told that he's been entrusted with Ikuya Kirishima's care and training until Natsuya Kirishima returns. A frustrated Haruka challenges Hiyori to allow a swimming race to decide things. Hiyori agrees but Makoto races instead, as both Hiyori and he specialize in the backstroke. Makoto loses, but thinks all is well until Hiyori still denies them seeing Ikuya, saying the swimmer's health is fragile and that Haruka is a negative influence.
