Kotaro appears to be modled after Elvis Presley, and is always seen with a comb in his hair (or hand). He has the longest legs out of all of the Eyeshield 21 characters.
He first appears at Deimon High, looking for the '60 Yard Magnum' Musashi, whom Kotaro wished to play against. However, unable to find him, he returns to Bando, but appears a few days later. Alongside Sena and Tarō Raimon, he assumes that Muro Satoshi is Musashi, and the three challenge Muro to a penalty shootout.
- His favourite food is meat (it is not specified which type).
- His favorite animal is the monkey because it is pure and honest.
- The person he respects the most: Elvis Presley
- The most important thing in life: Zeal
- Occasionally he opens up his switchblade comb too fast and hits his hand.
