KADOKAWA Corporation (Headquarters: Chiyoda City, Tokyo; Director, Representative Executive Officer, President & CEO: Takeshi Konno; hereinafter 'KADOKAWA') has released 'Kutakuma: The Bears' Quiet Rebellion to Protect Their Hearts' (author: Kutakuma) on Thursday, July 16, 2026.

A condensed collection of relatable 'you know how it is' moments for every working professional surviving an unreasonable world!

The popular series 'Kutakuma,' serialized on the author's X (formerly Twitter) account and instantly gaining thousands of reshares, is finally being published as a long-awaited book. The story follows two main characters: 'Kutakuma,' a gloomy, overworked office worker whose charm lies in his eyes, and 'Ururun,' a sharp-tongued, aggressive employee who flips off her toxic boss in her mind.

Mornings of despair as the thermometer shows a normal temperature (36.5°C) despite overwhelming fatigue

Frustration at receiving an email on Friday night demanding a response by Monday morning

Instant spiritual ascension upon seeing the amount of tax deducted from the paycheck

Bowing deeply while mentally spewing venom

Even while questioning, 'Am I working not to die, or dying because I work?'—these resilient individuals head to the office every day. Their inner struggles are portrayed with subtle humor that makes you chuckle and, somehow, feel comforted.

Preserving the vibrant, colorful atmosphere of its social media origins, the book delivers the full story in full color, presenting the heartwarming yet heartbreaking theater of two lovable overworked 'salary bears.'
