Takumi is Yui's 15-year-old childhood friend and a 3rd year middle school student. He's blunt but takes care of people. His family runs a guest house.
Takumi is suspicious about Rosemary after seeing him with Yui every time an Ubauzo appears. He feels the need to protect Yui from danger, but hesitates after remembering his father's words, and feeling embarrassed about the costume he'll have to wear. Takumi also notices that he and Rosemary both have a Delicious Stone.
In order to protect Yui from the Bundle Gang he transforms into Black Pepper, a Cook Fighter.
