Makoto Nijigahara is Happy Rainbow's top designer—basically the creative force behind the brand's whole aesthetic. He's got kind of an unusual personality: quirky, high-pitched voice, and admittedly pretty effeminate in his presentation.
Fans often note that he wasn't always the warmest person around. Before meeting Otome, he was rigid, demanding, and honestly pretty hard to like. But that relationship genuinely changed him. He went from being all strict rules and no fun to actually believing that love is power—and it shows. He's way more open and friendly now, way more willing to connect with people. It's one of those character turns that actually feels earned.
He's also tight with Green Grass, which makes sense given how his whole worldview shifted toward being more social and collaborative.
