"Think before making your choice. That's your only job"
―Jackalope

Jackalope is supposed to be a UMA (unidentified mysterious animal) that lives in Wyoming, America. For some reason he's now a guard at Milgram Prison together with Es. He acts as a guide and teaches Es about their duties as prison guard.

Jackalope loves talking and is able to use human speech, but only Es can hear his voice. He is also very sensitive when Es uses words like "slow, short" and actions that humiliate him in some way as a rabbit.
