The role of Messengers is mainly to assist those chosen to become Kämpfers in understanding the rules and mechanisms of Kämper combat. They take the form of Entrails Animals, plush toys that are notable for having their guts sticking out. Many of them have been described in the novels as having voices similar to those of specific real-life voice actors, who would in turn do the voices for them in the anime.

Burnt Alive Lion (ヒアブリ ライオン, Hiaburi Raion?)
Voiced by: Kenji Utsumi The oldest Messenger, its existence said to pre-date the Zōmotsu Animal toyline. The novel version of it does not have its guts hanging out of its body like the Zōmotsu Animals after it, but the anime version does. It has the same shape as a character which Kaede imagined before, with a voice similar to that of a voice actor who performs voice-overs for foreign movie stars. Kaede got it by mere chance though it is very scarce. In episode 11 of the anime, it reveals the reason behind the Kämpfer battles.
Hit-and-run Hippopotamus (ヒキニゲ カバ, Hikinige Kaba?)
It was the Messenger for Tamiko Shinomiya. It has turned back to a plain doll since she disappeared. Kaede presented another Hit-and-run Hippopotamus to Midori Kuzuhara.
