John

John is a standout figure among the shadow residents of the Shadow Mansion, known as the master of the living puppet Shaun. His personality starkly contrasts with Shaun's composed demeanor—John is boisterous, straightforward, and brimming with raw energy. Though Kate has jokingly remarked that he isn't the sharpest mind around, his immense reserves of shadow-ash power and destructive capability have proven decisive in critical moments. Having fallen head over heels for Kate at first sight, he boldly proposed to her on the spot. This unfiltered sincerity and complete lack of ulterior motives make him one of the most trustworthy allies in Kate's camp.
