Momotaro Mikoshiba (御子柴 百太郎 Mikoshiba Momotarou) is a supporting character in the anime series Free! beginning with Free!-Eternal Summer-. He is Seijuro Mikoshiba and Isuzu Mikoshiba's younger brother and a high school student at Samezuka Academy. He is a backstroke swimmer that Seijuro predicts will be the team's "fearsome new face." [3] As of the end of Free!–the Final Stroke– the second volume, he is a third-year student as well as the swim club's captain.*[4]


Momotaro has golden eyes and dark orange hair just like his brother, but in a messier fashion. He has a healthy, slightly tan, complexion and is of average height and build.


He possesses a happy-go-lucky termperment and enjoys the company of girls alot. He's like his older brother, both in terms of swimming and personality. And just like Seijuro, he has a crush on Gou Matsuoka at first sight, saying that she's "pretty cute."[1]


Momotaro claims to have won many races in his previous school and that there's not a single person in his hometown who hasn't heard of him. When meeting Rin Matsuoka, Sosuke Yamazaki and Aiichiro Nitori for the first time, he states that the swimmers he competed against used to call him The Sea of Japan's Sea Otter.[1]

  • His hobby is hunting for stag beetles.[1] The biggest one he caught was about 8 centimeters. [5]
  • His motif animal is a sea otter.
  • His favorite proverb is, "Even Homer sometimes nods."[1]
  • His favorite dish is fried eggs.[1] Other favorite foods include triple-cheese burgers and chocolate pudding ice cream.[6]
  • Momotaro owns a pink T-shirt with a boy coming out of a peach at the back. This refers to a folk tale about an old couple who found a giant peach with a little boy inside, naming him Momotaro because "momo" in Japanese means "peach."
  • His favorite pasta dish is vongole.[5] This is most likely a reference to his motif animal, the otter, as one of the main ingredients in this dish is clams, with vongole being Italian for clam and clams being a common part of a sea otter's diet.
  • His English voice actor, Jerry Jewell, also voices Mr Tachibana.
  • Those born under Sagittarius are giving, optimistic and humorous, but can also be impatient and impulsive, promising more than they can deliver. They enjoy freedom and being outdoors, and dislike clingy people and details. Those born on Dec 6 see everyone as equal idealists to themselves and are challenged to view others and the world realistically. Traits are affected by the position of the moon and other planets at the time of birth.[7]
