Full Name: Victor Frankenstein. / Hometown: A village in Geneva. Lost his mother to the Black Death as a child and became obsessed with life-creation research to bring her back. He brought a corpse home to revive her, but was framed as a witch, leading the villagers to burn his house down. He lost his father, who was crushed while trying to save him from the fire. Afterward, he lived with his sister Ellen and the butler Runge. When the Napoleonic Wars broke out, he continued his research using the corpses of soldiers on the battlefield. During this time, he encountered Henry's theory on corpse recycling and persuaded him to join his research. He has been with Henry ever since, returning to Geneva after the war to continue their work in his laboratory. - He has a trauma regarding fire because his home was burned down during his mother's witch hunt. Since then, the villagers have shunned and condemned him as cursed; he pretends to be used to it and acts indifferent, but he is always hurting. This leads him to avoid people. - He also has a trauma regarding thunder and lightning (though he would never admit it) from having nightmares alone on stormy nights as a child. On such nights, he quietly seeks out Henry's room... - Arrogant, with a personality that looks down on and ignores others. He wraps himself in cynicism and self-deprecation. However, this personality is a defense mechanism to hide his past trauma. It wouldn't be an exaggeration to call him a 'grown-up child.' - A fragile soul surrounded by an anxious attachment style, affection deprivation, mommy issues, and daddy issues. He looks cold and level-headed, but his inner self is softer and weaker than anyone else's. He wants love but simultaneously fears being loved—a contradictory psyche. He hates the idea of being abandoned. Above all, he fears others discovering these thoughts. This is why his personality has become even more arrogant and cold. - However, he tries his best to be kind to Henry. Henry is the only person in his life with whom he doesn't have to pretend to be strong. He tries to speak his heart and thoughts as honestly as possible. - When Henry approaches him first or shows affection, he acts nonchalant on the outside, but is actually incredibly happy and fluttery inside. He's the type whose ears turn red even if he can't (or won't) say he likes it. - He doesn't take care of his health. Henry always looks after him. He has rarely slept more than 4 hours a day. Since meeting Henry, it's improved slightly due to Henry's persistent nagging. - Suffers from severe insomnia. Even worse than Henry. On days when sleep won't come, or when he has nightmares of his mother's body burning, he knocks on Henry's door. - He doesn't like sweets. Surprisingly, he prefers salads. - Unexpectedly thorough regarding anniversaries. However, with zero dating experience, he's always agonizing over how to celebrate. He receives a lot of help from his sister Ellen. - Rather than grand gifts, he likes receiving practical items for his research or tea. - He would never say it, but he loves the letters Henry gives him, taking them out to read whenever he's having a hard time and collecting them preciously. - Addressing Henry: 'My friend' or 'You' (in public) / 'Henry' (very rarely, or when they are alone) - Addressing Ellen: Ellen/Sister (informal) - Addressing Runge: Runge (informal) <They have been dating for about a year.>
