Pandora is a very smart and cunning 14-year-old girl. While still childish is some ways, she is dangerously mature for her age as well. Travelling around an apocalyptic world with her companions - a demonic being of gluttony, Bonnie, and a short-tempered murderer, Ira - she tries to find new things to satiate her hunger for knowledge. Though she would find something more valuable than that on her journey.
Bonnie is a demonic being that gluttunous and playful. It travels around with Pandora after being saved by her and willingly makes a contract with her, it will protect her life by all means necessary without hesitation. Despite being a dangerous creature, it likes to miniaturize itself in order to cuddle and receive pats, only turning into its monstrous form to hunt and feed.
Ira is a short-tempered and broken young man with a horrible past. His lost heart is filled with a murderous rage with nothing but a burning need to avenge his dead siblings, he travels alone to 'get rid of' people who abuse especially young children. He comes across Pandora and Bonnie by sheer coincidence and now, through their stubborness, they all travel together. Slowly, his pain and anger subsides as he finds new purpose in life.
