The "useless", untalented baker-sidekick.
Baking: He can do the basics, but can't come up with something new or original. He, at first, lacks solar hands, something that Azuma has. Tsukino puts him through a tough training regimine to give him modified solar hands.
Family: Father was who inspired him to become a baker. Kawachi wants to fulfil his father's dream of entering Pantasia and becoming the best baker there. His father died in a fire while practicing for a Pantasia entrance exam (the last of many).
Pantasia Entrance Exam: Kawachi uses Azuma and his crescent moon croissant to pass the entrance exam.
Southern Tokyo Branch Store: Kawachi is invited to work there by Tsukino when he refuses the position offered to him at the main branch.
Talent: Has extreme reactions/transformations after tasting yummy food.
