Gaku works at a cat cafe alongside his sister Kaoru and their coworker Kunagi, where he primarily handles serving food and drinks to customers.
He's got purple eyes, a short beard, and typically dresses in a white shirt paired with a yellow cat-themed apron and dark blue jeans. Known for his charismatic personality, Gaku comes across as genuinely friendly with patrons and often pitches in with Kunagi and Kaoru to give cat-care advice when it comes up—usually emphasizing that keeping cats healthy isn't nearly as simple as people assume.
That said, he has a strict side. Break the cafe's rules and you'll see him snap. He famously knocked out a customer named Tanishi for wearing cologne near the cats, making it very clear that kind of thing isn't tolerated.
When the nyandemic hit, Gaku was among the first to get infected. His own cat contracted the virus after coming into contact with the origin cat, and Gaku caught it from there while trying to evacuate everyone from the cafe. Even as he began showing physical symptoms, he made a deliberate choice to slow down the spreading cats, buying time for the others to escape. Rather than resist what was happening to him, he seemed to accept it peacefully—even embracing his transformation as it began.
