The boy Fuka loved in Osaka. However, upon learning that Fuka had her first kiss from Akito during kindergarten, he assumed she already had a boyfriend and started avoiding her. Fuka interpreted this as Takaishi not liking her because she was tainted by Akito's kiss. When Takaishi visits with a group of Fuka's friends from Osaka, he discovers the misunderstanding and asks Fuka out, but she declines, stating that it wouldn't work since they live in different towns.
Later, Sana and Akito find his new address and talk to him, learning that he broke up with his girlfriend because he still has feelings for Fuka. They give Fuka his address and phone number so she can call him anytime. She is unsure whether she should call him or not.
In the anime, Fuka gives up on Takaishi after meeting his new girlfriend, Shizu. But after Fuka breaks up with Akito and Takaishi breaks up with Shizu, they resolve their misunderstandings and become a couple.
