Tei'iku Chuutoku

In the anime, she is Kakuka's companion who tries her best to keep Kakuka out of trouble, often cleaning up the messes she makes from her nosebleed episodes. She's a good ventriloquist, usually utilizing it on her head ornament she named Houkei. She is also seeking to serve under Sousou as a strategist, and is accepted as such.

In the visual novel, she is the silent adviser girl and a new character in the sequel, Shin Koihime Musou. She is most notable for always carrying a lollipop, as well as wearing a head ornament that somehow reflects her emotions.
