Chouhi Yokutoku

Visual novel version Chhi joins Kazuto along with Kanu after the two discover him together. Unlike Kanu who holds a more reserved Masterservantlike relationship with Kazuto she treats Kazuto like an older sibling and calls him big brother similar to how she treats Kanu. As a powerful character Chhi 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. Anime version Chhi 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 capable of competing against Kanu in armed melee combat. She is one of the main characters and the first person to join Kanu. Chhi 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 Rybi of becoming Kanu little sister as Chhi was already made a vow with Kanu to be her little sister but accepted when Rybi decides to make Kanu her little sister instead. By the third season she has accepted Rybi as her other older sister and even calling her Touka neechan. She wears a hairpin in the shape of a round yellow smiley face that changes expressions according to Chhis mood. Before she joined Kanu she was a leader of a kids bandit group called Rin Rin Bandits. The reason she made that group was so she wouldnt feel alone. When she was very young a group of bandits killed her parents and was taken in by her grandfather. But when he passed away she was all alone until she met Kanu. She only approves her friends and family to call her Rin Rin her real name. wikipedia.org
