Jack Mouton

Jack stands at 155cm tall.

His image color is Envy Green, reflecting his sly, attention-catching aura.

He often appears as the fashion model for Veuve Elizabeth’s apparel brand, Rouge Lien.

Jack is bold about his mischievous nature; he doesn’t bother hiding his cunning side.

He’s got a little devil’s spirit, thriving on tricks and playful provocations.

Jack’s favorite things are sweets and games, mirroring his youthful and somewhat rebellious heart.

Even when he finds himself in trouble, he faces consequences with a smirk, never afraid to speak his mind.

Hailing from England, Jack shares a complicated past with his twin brother, Robin Laffite.

He once became so jealous of Robin’s singing voice that he attempted to kill him, but couldn’t leave a single scratch on him.

After that, Jack disappeared for a time, only to eventually reunite and reconcile with Robin.

Jack helps Veuve Elizabeth with her fashion brand, serving both backstage and center stage as her stylish image model.

Jack possesses immortality as a vampire, making him difficult to kill—even after his heart was shattered.

Despite being mortally wounded after breaking a key vampire law (by turning Robin into a vampire), he revived thanks to his undead nature.

His heart, however, remains cracked, suggesting the sands in his hourglass may be running out.

Jack is capable of protecting those he cares for, even taking blame for actions that aren’t entirely his own.

Robin Laffite is Jack’s twin brother; their relationship is charged with jealousy, intense rivalry, and eventual forgiveness.

He is a close accomplice of Veuve Elizabeth—helping with her brand and acting as her primary model.

When Hyde Jayer discovered Jack had fed on a human, Jack shielded Robin by taking all the responsibility himself.

His birthday is October 22, making him a Libra.

Voice acting is provided by Shogo Yano.

Jack is deeply committed to his pranks—mischief isn’t just a pastime, but a defining trait.

He sincerely loves fashion, thanks to his connection with Rouge Lien.

Visually, Jack is associated with the color Envy Green.

“Hey, so what other weaknesses do you have?”

Playful but probing, Jack’s questions often dig deeper than they seem.

The Twin Struggle

Driven by envy, Jack’s jealousy over Robin’s voice led him down a dark path, even intending to kill his own brother.

He failed to harm Robin, realizing the depth of their bond—this experience changed both brothers.

Breaking the Law

With Robin’s consent, Jack turned him into a vampire.

This act violated the laws of the Red Moon, resulting in Jack’s heart being shattered and causing him to die, if only briefly.

Thanks to his immortality, Jack revived, but the cracks in his heart remain—a constant reminder of his sacrifice.

Protecting Robin

When Hyde Jayer uncovered the truth about Jack feeding on a human, Jack took full responsibility to shield Robin from blame.

Despite appearing sly and mischievous, Jack’s loyalty to his brother shines when it matters most.

Jack Mouton is a key member of VISUAL PRISON’s universe, known for his tricks and emotional complexity.

His story is full of chaos, fashion, and personal reckoning—a true small devil with a big impact.
