Takeshi Yagashira, the son of Seiji Yagashira and father of Kiyotaka Yagashira, serves as manager of the antique shop Kura, owned by his father, though he entrusts the shop's daily operations to his son. Beyond his work at the antique shop, Takeshi is a successful novelist. He maintains an exceedingly polite manner, a demeanor cultivated during his upbringing in Tokyo, which also accounts for his use of standard Japanese rather than the local Kyoto dialect.
