Doronpa, an American obake from Texas, resides in Japan with his human companion Kaminari. His light pink form features distinct legs and a prominent red star on his stomach—a detachable emblem of his American heritage, adorned with a Stars and Stripes motif that fuels his supernatural abilities. Intelligent and dexterous, he masters transformation, morphing into objects or individuals to execute playful schemes, such as impersonating his rival Q-Taro to stir mischief in Q-Taro’s homeland. Their rivalry ignites from U-ko’s admiration for Doronpa’s wit, prompting him to prod Q-Taro during encounters. Beneath his trickster exterior lies a warmth that endears him to Kaminari, P-ko, and others.

Having once dwelled in a Texan squire’s estate, Doronpa occasionally grapples with loneliness in Japan, yet finds solace in friendships. A hamburger enthusiast born on March 27th, he revels in antics like boasting American ghost superiority or shapeshifting into a dog to exploit Q-Taro’s canine phobia. Though he disrupts Q-Taro’s life with pranks, his intent remains harmless, blending mischief with an innate kindness. Bonds with both obake and human circles underscore his multifaceted connections, where rivalry coexists with camaraderie.
