Kakeru Keshi is a manga assistant at G-PRO, the studio led by Kakushi Gotou. His primary responsibility is erasing mistakes on manga manuscripts, a role directly tied to his name—a pun on the Japanese phrase for "using an eraser" (消しゴムかける, *Keshigomukakeru*). As the newest team member, he frequently needs guidance from senior assistants Aogu Shiji, Rasuna Sumita, and Ami Kakei to navigate the studio's routines and eccentric work environment. This newcomer status results in colleagues often explaining office practices and the ongoing efforts to conceal Kakushi's secret profession from his daughter.

Kakeru possesses a cheerful demeanor and cooperative attitude. He actively participates in G-PRO's operations, including the collective mission to prevent Hime Gotou from discovering her father's true occupation. He assists in tasks such as relocating manga materials and maintaining studio secrecy during Hime's unexpected visits. His interactions with colleagues showcase a friendly and occasionally naive personality, especially as he adapts to the studio's unconventional dynamics. His role is consistently that of a supporting figure within G-PRO, contributing to daily functions and the commitment to preserving Kakushi's secret.
