Ralph

Ralph is a minor character in Free!'s third season, Free!-Dive to the Future-. He is identified as  Albert Volandel's coach based on his behavior and attitude when interacting with the Swedish swimmer, whom he calls "Al," as well as the fact that he is allowed to be on deck with the swimmer during a heat, a courtesy allowed only to coaches. Ralph is responsible not only for overseeing Albert's training and competition schedule, but for his safety, which includes knowing his whereabouts at all times. He is a strict coach, but a highly effective one.

Appearance
Ralph is a tall man with a toned build. He has thick brown hair that is swept to one side, partially covering his right eye. He is seen wearing a pale blue polo shirt, green trousers and red sneakers.

Personality
Ralph seems to be a somewhat severe individual who takes his job of working with Albert and keeping him safe seriously. Albert's penchant for sneaking off to be "on his own" is risky for a world record-holder, especially for someone who may become an Olympic champion and this habit frustrates the coach. Once he finds Albert, Ralph chides the swimmer for eluding supervision again, ignoring Haru's presence altogether.

The next time Ralph is seen is at the "friendly competition" at the training center in front of all the attendees, including Haru. Already startled by the swimmer's prowess from an earlier impromptu race at the center's pool, Haru finally learns who Albert Volandel is, along with his multiple honors. Ralph stands behind his protégé as he is introduced as the current world record holder in both the 100m and 200m freestyle. His expression is one of challenge as sizes up the would-be competitors looking to take on the world champion. It is in striking contrast to Albert's demeanor and visage, which is relaxed anticipation for the upcoming event.
