The upbeat and energetic former J-Chair (Jack's Chair), he is one year senior to Amu.
As the captain of the Soccer Club, he is athletic and has good reflexes.
He has since graduated, which is the reason he has been replaced. Saaya appears to have a crush on him, as when she saw the picture of him with Amu, she was furious. Through the power of the Humpty Lock, he and Daichi managed a Character Transformation once, forming "Sky Jack." The words 'Kick, Stack, Trap and Shoot!' spark his Character Change.
As of chapter 31, Kukai's four older brothers are introduced. The first and oldest is Kaidou (海童, Kaidō), the second is Shuusui (秀水, Shūsui), the third is Unkai (雲海, Unkai), and the fourth is Rento (れんと, Rento). All of their names have kanji meaning either the sea, or sky, or have a relation to it, including Kuukai, but not Rento because his name has no kanji. This is possibly the reason why his Guardian Character is named Daichi, although without kanji, daichi (大地, daichi) means earth.
Kukai’s Guardian Character is Daichi.
Daichi is very good at sports and can't seem to sit still.
He was born when Kukai wanted to do many sports but had to choose.
He wears a sweatband around his head, shorts, and a sporty T-shirt.
When Daichi and Kukai do Character Change, Kukai becomes even more athletic and gains a star clip for his hair that looks like the same star on Daichi’s head band.
Daichi was able to Character Transform with Kukai once, resulting in "Sky Jack".
