Kaoru Ijuuin is one of Tada's oldest friends and hangs out with him in the photography club. He's genuinely good-looking when he's not talking—which, let's be honest, is basically never. The guy can't keep his mouth shut to save his life.
Cooking runs in his blood. His family owns a prestigious restaurant in Ginza, and he's expected to take over eventually, which means he's picked up serious culinary skills along the way. He's become a regular fixture at Tada Coffee Shop, so he's tight with both Grandpa and Yui by now.
The bond between him and Tada goes deep. Back when they were kids, Tada pulled him out of a dangerous situation, and Kaoru's never forgotten it—he genuinely sees Tada as his one true friend. That said, there's one major obstacle to his peace of mind: Nyanko Big absolutely can't stand him. Whenever they cross paths, Kaoru goes full defensive mode just to survive the encounter.
