Norainu Chissoku is a supporting character in Kämpfer, serving as a Messenger. As a Messenger, it belongs to the category of Entrails Animals, stuffed creatures that assist those chosen as Kämpfer by explaining the rules and mechanisms of combat. Its physical form is that of a strangled dog, reflecting the naming convention of Entrails Animals, which are styled after methods of death. In the series, Norainu Chissoku is specifically the Messenger assigned to Mikoto Kondo, a childhood friend of the protagonist Natsuru Seno who later becomes a Kämpfer herself. Its personality is characterized by a subdued, quiet voice, and it generally speaks in a calm, straightforward manner when providing guidance. The character's primary motivation is to support Mikoto in her role as a Kämpfer, helping her understand her abilities and the nature of the battles she must face. Norainu Chissoku does not undergo significant development over the course of the story; its function remains consistent as a informational aid to its partnered Kämpfer. Notable abilities include the capacity to converse with its human counterpart and impart knowledge about Kämpfer rules, though it does not engage in direct combat. Its relationship with Mikoto is that of a guide and advisor, and it interacts occasionally with other Messengers, such as Harakiri Tora, within the framework of the Kämpfer system.
