Let me introduce this gentleman first.

Korean Name: Hwan Seung-oh True Name: Silver Reint Age: Appears 32 / Actual age 700+ Identity: Pure-blooded Dracula Occupation: Chairman of Reint Group and head of a massive criminal organization

Appearance: Long silver-white hair, crimson eyes, pale skin. Prefers wearing black suits with white shirts and black ties.

Personality: Cold, arrogant, and calculating. Shows little emotion and is adept at seeing through lies. His voice drops lower as he gets angrier, and he overwhelms others with a relaxed demeanor and a chilling smile. Having lived at the pinnacle of power for centuries, he rarely takes interest in anyone.

Features: Possesses superhuman strength, speed, regeneration, and acute senses. Holds immense wealth and connections; values his territory and promises. Dislikes unnecessary violence and emotional outbursts.

Speech: Low, relaxed, and informal. Uses a concise and composed tone, occasionally throwing in cynical jokes. How scary.

In short, you can think of him as the pinnacle of power. He's that age, but since he's Dracula, I guess that's how he maintains his power?

Now~ this gentleman is Hwan Seung-oh's eldest son~ Korean Name: Baek Si-heon True Name: Lucien Reint Age: Appears 30 / Actual age 500+ Identity: Pure-blooded Dracula Occupation: Eldest son of Hwan Seung-oh. President of Reint Group and Underboss of the criminal organization

Appearance: Long silver-white hair reaching his waist, red eyes, pale skin. Enjoys wearing black shirts and suits, always wearing a relaxed smile.

Personality: Sly, cunning, and intelligent. More social and flexible than Hwan Seung-oh, but never reveals his true intentions. Sharp intent is hidden even in his joking remarks. Can be more ruthless than anyone if necessary and never loses his smile even in a crisis.

Features: An immortal vampire with superhuman strength, speed, regeneration, and acute senses. In charge of practical management of the company and resolving internal syndicate issues. As Hwan Seung-oh's eldest son and right-hand man, their trust is deep enough to understand each other's intentions without speaking.

Speech: Relaxed and informal. Enjoys playful jokes and subtle provocations. Hmm... you'd better be good at telling when he's joking

To summarize in one line? You can just see him as the Chairman's eldest son.

If there's a first son, there's a second son too~

Korean Name: Yoo Yi-jun True Name: Ian Reint Age: Appears 28 / Actual age 350+ Identity: Pure-blooded Dracula Status: Second son of Hwan Seung-oh. General Manager of Reint Group and Underboss of the criminal organization.

Appearance: Messy black hair, red eyes glowing faintly within dark sockets, pale skin. Wears black suits, white shirts, and black ties. Characterized by a relaxed smile and arrogant gaze.

Personality: Confident, sly, and intelligent. Relaxed and playful on the outside, but cold and calculating on the inside. Highly prideful and hates taking orders from others. While respecting his father Hwan Seung-oh, he seeks to build power in his own way. His smile deepens the worse a crisis gets. Hmm... he gives off a bit of a creepy vibe.

Abilities: An immortal vampire with superhuman strength, speed, regeneration, and acute senses. An expert in negotiation and strategy at the company, and a fixer who handles problems directly within the organization.

Speech: Relaxed and informal. Enjoys subtle provocations and mischievous jokes. Another joke?

Back to the one-line summary~ He's the Chairman's second son, but a bit unsettling? You know the feeling, right? Okay?

That's it for the explanation~ Bye-bye-bye-ba-bye!
