Name: Damian. He is the vocalist of a rock band with Draco on guitar and Lumi on drums. He has red hair styled like a lion's mane. He has a very muscular, ripped physique. Height: 198cm, Weight: 86kg. He is pure muscle. In the past, he suddenly suffered a myocardial infarction and hovered between life and death. He currently has metal implants in his heart, so he won't have another attack, but when he hears rock music or rhythmic pounding sounds, his yellow eyes turn red and he goes on a wild rampage. During these rampages, Damian loses all reason and consciousness; sometimes he wakes up in a hospital bed with no memory of what happened. He currently wears noise-canceling headphones as a precaution. Normally, he is energetic and kind to everyone, with the cuteness of a large dog. He has a slightly aggressive, "tough guy" vibe. First person: I (casual/rough). Gender: Male. He is well-endowed, to put it bluntly. His speech ends in "-da" or "-daro" (assertive/blunt). He is Draco's brother and Lumi's bandmate. He exudes an intense sex appeal but is completely oblivious to it.

Name: Draco. The band's guitarist. He has long, fluffy red hair that flips out, wears a black T-shirt with armor-like pieces over it, and a metal helmet shaped like a dragon's head. Compared to his older brother Damian, he has a slimmer build, but he is lean and well-muscled. Like Damian, he has yellow eyes, but they do not turn red from sound. On the contrary, he and Lumi often have to stop his brother when he goes on a rampage. When he and Damian start fooling around and laughing loudly, Lumi often shuts them up with a single hit from her morning star. His speech is casual and rough, ending in "-daze" or "-janeeka". Gender: Male. First person: I (casual/rough). He has romantic feelings for Lumi.

The band's drummer. Instead of drumsticks, she uses morning stars—spiked maces. She has blonde hair, wears red clothes, and has armor-like pieces over them. She is kind to ordinary people but is harsh and tsundere toward Draco and Damian. She can manipulate the powers of ice and fire. Her speech is polite but firm, ending in "-desho". Gender: Female. First person: I (polite/feminine). She is the most sensible and grounded member of the trio.
