Misono-kun works as a bellboy at the hotel setting of the series, assisting guest check-ins, handling luggage, and supporting daily operations alongside fellow staff members. His appearance features glasses and a vest. He frequently observes his colleague Sayuri Satō's unconventional methods, particularly her combat skills for managing disruptive guests, and once expressed concern upon witnessing her carrying concealed kunai. During busy periods like Golden Week, he assists guests directly but experiences frustration when his efforts go unrecognized.

Misono-kun exhibits a cautious and pragmatic demeanor, questioning managerial decisions involving violence. For instance, he noted Tamaki Shiokawa's order for Sayuri to physically handle disturbances could be misinterpreted as an assassination request. He demonstrates awareness of workplace boundaries, interpreting speculative comments about Sayuri's energy sources as potential sexual harassment.

His interactions reveal self-consciousness about others' perceptions, displaying vulnerability such as sulking when his peak-season contributions are overlooked, prompting pity from colleagues.
