CAST

Hikaru Gero (VA: Haruki Ishiya)
Heir to the “Poison Master” Gero Family, one of the Five Great Families of “Masters,” and a top-class assassin. Having lived his whole life in the underworld, he has zero experience with romance and is awkward around women. Driven by the need to continue his family line, he begins his search for a bride. His hobby is collecting DIY candies.

Mei Kinosaki (VA: Shion Wakayama)
A brilliant marriage swindler who boasts they can seduce almost anyone—male or female—in under 30 seconds. After crossing paths with Hikaru, they unexpectedly end up helping him with his marriage quest. Loves delicious food and, despite their appearance, has a surprisingly huge appetite.

Kyoko Himekawa (VA: Anna Nagase)
She works to recover art that has been unjustly taken and return it to its rightful owners. Highly skilled in communication, she can become friends with anyone, yet rarely speak much about herself. She has a deep love for sharks, and collects shark-themed merchandise and movies.

Shiori Ureshino (VA: Asaki Yuikawa)
A college student and the heir to Balzak, a major party supply corporation worth 1.5 trillion yen. Shy and overly considerate of others’ feelings, she is aware of this trait and wishes to change. Her hobby is performing magic tricks, and she loves making people smile.

Kimie Arashiyama (VA: Hinano Shirahama)
A “Hamster Master,” a branch descendant of the “Beast Master” bloodline. Sirius, her partner, is highly skilled in intelligence work. During her childhood, she was once saved by Gero, which led her to be his secret admirer. She currently works at a small-to-medium-sized advertising agency as she is searching for her long-lost brother.

Shizuku Ushio (VA: Mariya Ise)
“Water Master.” A businessman of the underworld. Highly businesslike and thorough in her work, she completes every task with precision. She’s always dressed in a diving suit.

Genya Naruko (VA: Soma Saito)
A direct descendant of the “Sound Master” lineage. Possesses a unique aura and distinctive way with words. Not only is he extremely handsome, he is highly popular among the ladies. Since he needs to stay relaxed to use his abilities, he’s come up with his own unique ways to unwind.

Piichi Nakagawa (VA: Simba Tsuchiya)
An ordinary human, but a genetic anomaly with abilities far beyond a “Master.” He possesses exceptional information-processing skills along with superhuman physical abilities. Needs to sleep more than 10 hours a day to function properly, but after sleeping, his body can heal almost any injury or ailment. In terms of pure talent as an assassin, he is among the very best in the modern era.
