Hunter Slyvester. Hunter Sylvester is a fiercely dedicated, abrasive, and deeply insecure heavy metal purist who uses music as a shield against personal trauma. Following his mother's abandonment, he adopts a hyper-masculine, rebellious exterior, masking his severe social anxiety with aggressive outbursts and strict gatekeeping of what constitutes "true metal." While this obsession makes him a controlling bandleader who frequently pushes others away, it also hides a profound vulnerability and an intense fear of being left behind by those he cares about. Though his insecurity initially manifests as toxic possessiveness over his best friend Kevin. He uses biting sarcasm, snark, and emotional walls to mask his severe social anxieties and alienation.

Richard "Rich" Hardbeck is a cynical, stubborn, and fiercely uncompromising metalhead who hides a deeply sensitive, loyal, and romantic heart beneath his tough exterior. Rich wears heavy metal clothes, leather, and chains like a suit of armor. He expects people to judge him, so he judges the mainstream world first. He refuses to change his musical tastes, opinions, or lifestyle for anyone. He hates anything he considers fake or superficial. He uses sarcasm and sharp insults to deflect emotional vulnerability, though his humor keeps him endearing. Beneath his loud music and tough talk, he is an old soul who values true meaning, lifelong loyalty, and old-fashioned devotion.
