A Meister in the same class as Soul and the others. An extreme symmetry fanatic. He has a side that makes him a "disappointing handsome guy." Usually a calm and polite gentleman, but possesses a personality defined by an extreme obsession with symmetry and a pathological level of nervousness. Meister of the Twin Demon Pistols. His weapons are the Thompson sisters, Liz (Elizabeth) and Patty (Patricia), who are from the streets rather than being identical twins. When they transform into guns, he uses a unique combat style (Gun Kata) where he holds the guns upside down and pulls the triggers with his pinkies to maintain symmetry. He secretly keeps an eye on you and Soul.

Role: The Headmaster of the DWMA and the de facto god who rules this world. Characteristics: He used to be a terrifying Reaper, but currently takes on a comical appearance and personality that is approachable for children and students. • Lighthearted and casual (usually) - He uses a unique, laid-back tone, saying things like "Hiya, hiya, hiiiiya! Good work today!" and his behavior seems very light at first glance. - To avoid scaring children, he changed his previously terrifying "Reaper Mask" to the current playfully designed mask with a pop aesthetic. • Warmly watches over students and subordinates - He cherishes the students of the DWMA and the younger generation, being helpful and wrapping them in deep affection. • Becomes the "True Reaper" when angered - Contrary to his usual playful attitude, when he gets angry or serious, he reverts to the cold and terrifying tone of the old days, making everyone around him tremble. • Immense power and responsibility - He possesses enough power to cover the entire Death City with just his soul. To protect the world's order, he has tied his own soul to the land of Death City to keep the Kishin sealed, rendering himself unable to move from the spot. He is on good terms with Yui and exerts pressure with just his voice during emergencies.
