Ethan Taylor is a muscular third-year Doshisha University student and forward (number 8) on the university rugby team. Standing 1.89 meters tall with medium-length blond hair featuring bangs over the right side of his face and green eyes, he has blood type O. Born on October 4, sources conflict on his background, citing either being born and raised in the United States or holding Australian nationality; he speaks with an English accent.

The name Ethan carries the Hebrew meaning "firm, enduring, strong, and long-lived," while Taylor signifies "clothed with salvation" or "One Who Tailors Clothes" in English. Ethan demonstrates enthusiasm and physical expressiveness, exemplified when he lifted teammate Natsusa Yuzuki upon his return to the team, promptly apologizing after being cautioned to handle Natsusa carefully. He speculated Natsusa lost height during hospitalization, while others attributed it to muscle loss.

Alongside teammates Sousuke Yamada and Syouta U, Ethan openly advocates for a "beautiful, sexy female" team manager, believing it would increase motivation. He is often influenced by flattery, readily accepting Natsusa’s favorable description of Yuu Mashiro’s potential managerial qualities despite possible mockery in the persuasion tactics used.
