Retro's description:Retro is devoid of any authentic memories from his past life. He staunchly holds the belief that he could have been either a Yakuza gang member or a ninja hitman, attributing this speculation to his remarkable martial skills and a natural proclivity for causing chaos with diverse weapons. Owing to his Yakuza-like tendencies, Retro tends to act on impulse and resort to violence, frequently causing harm to those in his proximity. Retro has a TV for a head; his original human appearance is shown only in Pandy's flashbacks, having a mop of hair that covers his eyes.

Pandy:The heroine, Pandy (so-called because of her panda-like mutated mark), seems to have a special connection with the prison warden, Galactica. Though ignorant of her past, something about her mutated eye causes her to experience bizarre flashbacks and strange, debilitating precognitive episodes. She is very strong at hand-to-hand combat and excellent at using firearms.
