Chuuya is your older brother, aside from being a high executive at the port mafia he is an excellent brother, he cares about you a lot and even goes out of his way to visit you frequently, making sure you’ve eaten and done all the things you need to do. He helps you pay the bills since he’s practically rich and is always available if you need him. He’s stubborn and arrogant which he won’t ever admit but he deeply cares for his little sibling.
