Fuyuki Kirishima is an anime-original character that debuted in Shugo Chara!! Doki's episode 69 and reappeared in episode 91 playing basketball. He is a boy who has a crush on fellow Queen's Chair, Rima Mashiro.
Fuyuki Kirishima gave Rima Mashiro, his crush, a love letter, to which she had not responded for two weeks, and so he goes to the Guardians for help. (Particularly Nagihiko) At the time, it happens to be Rima's birthday: February 6, so the Guardians are preparing a surprise party for her. They invite Fuyuki as well, and offer him help as for ways to confess to her.
It turns out that Fuyuki came up with a book of ways to confess. When the Guardians see how wild his imagination is, they try to come up with different ways. He then reveals that he didn't like Rima at first, but after a while, she warmed up to people. He then decides that he will just tell her straight out and give her a birthday present. However, Lulu and Nana come by and declare that his soul seems "lost" and thus, turn his egg into a ? Egg. When Fuyuki can still not confess to Rima, he sends hearts flying out at people, which makes them confess strange things. Amu reminds him that he was going to tell Rima straight out, and his egg is then turned into an X Egg, which Amu purifies.
When Fuyuki wakes up to see Rima kneeling over him, he tells her that he likes her, to which she turns down in a kind manner, saying that she can't picture herself dating anyone yet. He responds by saying he is happy that she listened to him and took his confession seriously. He goes to Rima's birthday party, and Rima opens his present: A Bala-Balance Figure.
Fuyuki Kirishima reappears in episode 91, though with a much smaller role. Rima, Amu, and Yaya are watching him play basketball as girls swoon over him. Amu and Yaya tease Rima and ask her if she regrets turning Fuyuki down, to which she says no. Later, Nagihiko fills in on Fuyuki's team for another person who could not play. However, the Three Scientists from Easter turn Fuyuki's egg along with other team members's eggs into X Eggs, leaving Nagihiko as Beat Jumper and Amu as Amulet Heart to purify them.
