Messengers

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.
