Description
Kokoro "Kokoron" Kakegawa is an 18-year-old idol (April 8 birthday) within the "Idol Bu Show" project, recognized by her blonde twintails and orange eyes. Standing 152 cm tall with measurements of B80 W56 H82 and blood type A, she enjoys rhythmic gymnastics, dance, and frequenting sweets shops, often with fellow idol Shiori Kirino around local live events.

She performs as part of X-UC, a new-generation idol unit guided by a music producer who is the reincarnation of Sengoku general Sanada Yukimura. Kokoro joined X-UC following a two-year hiatus after leaving her previous, unspecified idol group.

During the "Idol Bu Show" movie's "Battle Royale for the Tenka Bata," Kokoro competes with X-UC against other units, striving for top status through music sales, live attendance, and merchandise. The competition escalates when member Umino Risa flees before a key event, forcing X-UC to perform as a nine-member unit. Kokoro also features as an antagonist in the spin-off game "Idol Connect: Where Others Fail."

Her theme color is possibly blue. She shares her April 8 birthday with Rumi Wakui, Rio Teruya, and Biz Markie.
