Jackalope

Jackalope, (ジャッカロープ, Jyakkaroopu) is one of the two prison guards within MILGRAM along with Es. He's the head guard and the guide in the prison. He's 3 years old, and 80 centimeters tall which includes his horns.

He's voiced by Jun Fukuyama (福山 潤).

Background
Jackalope is a UMA (Unidentified Mystery Animal) but most often described as a rabbit. He supposedly resides in Wyoming in the United States, but is somehow a prison guard with Es in MILGRAM. He servers as a guide and helps Es learn about prisons and how to be a guard.

Personality
Jackalope is talkative and has a humorous personality, and can easily express himself using human speech. However, only Es can hear his human voice. He doesn't like when people refer to him as a "rabbit", and doesn't enjoy being called small either.

He does have somewhat of a creepy aura behind him, but what can be expected from the prison guard of a mysterious prison.

Trivia

 * Jackalope is based off of the mythical "jackrabbit" in North American folklore.
