Boris Cliff

Boris Cliff (ボリス・クリフ, Borisu kurifu) is a supporting character in BNA: Brand New Animal. He is the trainer for Nazuna Hiwatashi and is a leader in the Silver Wolf Order cult.

Appearance
Boris Cliff has long, blond hair and a square jaw. His outfit consists of a white coat, gray gloves, and a teal priest uniform. He is always seen wearing a gray mask with wolf-related embellishments.

After the destruction of the livestream concert he revealed his beastman form which is a multi-headed snake.

Personality
He is best described as cold, calculative, and manipulative. He took advantage of the commotion during Jackie's witch trial to convert more people to the cult and to seek residence for the cult in the Slums.

He is also creepy and caresses Nazuna like a doll. He treats her like his doll and uses her to further the cult.

Background
After Nazuna's transformation, she is abducted and taken to a research facility. Boris Cliff breaks her out and trains her to develop the transformation powers even further.

Eventually they join the Silver Wolf Order and Nazuna assumes a wolf appearance and the role of Death Rube. He continues to serve as her trainer and pull the strings behind the scenes.

Brand New Animal
Boris Cliff and the Silver Wolf Order sail to Anima City and arrive at the Slums. He appeases to the residents of the Slums and with the help of Nazuna's wolf appearance, they all bow and accept the cult with open arms. The cult sets up residence in the area and await a meeting with the Mayor. At night, Boris Cliff is seen caressing Nazuna as they discuss matters concerning the Mayor. Michiru also meets with Boris and is disgusted by him.

Trivia
Boris' appearance, a silver mask covering his eyes and blond hair, as well as his voice actor Takehito Koyasu, are a reference to the character Zechs Merquise from the anime series Mobile Suit Gundam Wing.
