Chōhi Yokutoku (張飛 翼徳, Zhang Fei - Yide)
Real name: Rinrin (鈴々, Lingling)
Voiced by: Miya Serizono (visual novel), Hiroka Nishizawa (anime)
Visual novel version
Chōhi joins Kazuto along with Kan'u after the two discover him together. Unlike Kan'u, who holds a more reserved Master-servant-like relationship with Kazuto, she treats Kazuto like an older sibling and calls him "big brother," similar to how she treats Kan'u. As a powerful character, Chōhi has the strongest Damage ability when used as a general in the game. However, she has no defense technique when used as a commander, thus making her unfit to be one.
Chōhi is a talkative and always cheerful girl. Although she is small and very smart in some things, she is naive in others, yet very powerful and strong. She is one of the main characters and the first person to join Kan'u. Chōhi will also be very dedicated to her duty no matter what the cost to her (in one episode, for example, she fights bandits despite having a cold.) During the second season, she was opposed of Ryūbi of becoming Kan'u little sister as Chōhi was already made a vow with Kan'u to be her little sister but accepted when Ryūbi decides to make Kan'u her little sister instead. By the third season, she has accepted Ryūbi as her other older sister and even calling her Touka nee-chan.
Not confused with Chouhi Ekitoku from Ikkitousen series and the historical figure.
