Samezuka BadgeMomotaro Mikoshiba (御子柴 百太郎 Mikoshiba Momotarō) is one of the main supporting characters in Free!-Eternal Summer-. He is Seijuro Mikoshiba and Isuzu Mikoshiba's younger brother and a backstroke swimmer, as well as a second-year high school student at Samezuka Academy. He is the "fearsome new face" to which his brother referrs.[3]


Momotaro has red hair just like his brother, but in a messy and straighter fashion. His eyes are a golden yellow and he has a healthy slight tan complexion. He's around average height for a male his age, as he is shown to be taller than Aiichiro Nitori.


Momotaro is a happy-go-lucky guy who likes hanging out with girls a lot. He's very much like his older brother, both in terms of swimming and personality. Just like Seijuro, he falls for Gou at first sight, saying that she's "pretty cute".[1]


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