Osomatsu Matsuno

The Eldest of the Matsuno Brothers. Osomatsu is the eldest of the six Matsuno brothers, all sextuplets who share the same birthday, making him the de facto leader of the group in their daily annoyances and schemes. He is often seen as the most responsible and mature among his siblings, despite his mischievous tendencies. His hair is styled in a spiky manner, reminiscent of a cat's ears, and he has a distinctive mole under his left eye.
