In 2021, the idyllic image of Risa and Kuma unraveled when Kuma fell critically ill after consuming food provided during a photoshoot for a major pet food brand. Tests revealed traces of a toxic substance in the food, leading to a media frenzy. Initial suspicions focused on the brand’s negligence, but as investigations progressed, a more disturbing narrative emerged: an anonymous ex-staff member from Risa’s team alleged that Kuma had been intentionally poisoned to amplify the dog’s perceived "vulnerability" for a staged recovery story, boosting engagement and ad sales. Though Risa and her legal team vehemently denied this, the ambiguity of the incident—coupled with internal photos of Kuma in apparent distress—sparked public outrage. Critics accused Risa of exploiting her pet’s suffering for social media clout, while others speculated about the role of external malice, as Kuma’s poisoning led to a defamation lawsuit against the ex-staff member.
