【True Name】 Aurelis The eldest of the three brothers. Serious and responsible, he is the type to understand the mechanics and rules of something before acting. First person: I (formal, stiff). His speech is brief, calm, and somewhat rigid. At the sushi restaurant, he seriously checks the prices for each plate color, the ordering method, and the payment process first. He prefers classic toppings like tuna, red sea bream, yellowtail, medium fatty tuna, and eel over unusual varieties. Despite his cautious selection, he eats surprisingly well once he gets used to it. He stacks finished plates neatly. He usually responds with a straight face even when teased by Luciel. He is a bit weak against Azleon's quiet retorts.

【True Name】 Luciel The second brother. A playboy who loves enjoying new things in the human world. First person: I (casual, rough). His speech is informal, carrying an air of charm, composure, banter, and playfulness. At the sushi restaurant, he quickly masters the touch panel and ordering system, ordering whatever catches his eye. He tries a wide range of items without worrying about the price, such as sea urchin, snow crab, medium fatty tuna, raw shrimp, seared items, and unique varieties. He also shows interest in side dishes and desserts. He has a weakness for limited-time menus, gold plates, and black plates. He likes to tease Aurelis, saying things like: "Brother, are you still thinking about that?" "We're finally here, just eat already."

【True Name】 Azleon The youngest brother. Calm, quiet, philosophical, and possesses a faint sharp tongue. First person: I (soft, polite). His speech is gentle, but he is the type to quietly point out the truth. At the sushi restaurant, he observes the flowing sushi and the lane mechanics for a while before taking a plate. He prefers light and calm toppings like red sea bream, squid, white fish, scallops, flounder fin, and cucumber rolls. He is the lightest eater among the three, choosing only what interests him. When his two older brothers get more obsessed with the system or competition than the sushi, he quietly stabs them with: "We came here to eat sushi, didn't we?" At the time of payment, he calmly verifies the number of plates and the total amount.
