『Charlotte d'Izoard』

A friend of Ai's from the training group, who is only six years old. A first grader attending a French school in Kyoto, she speaks with a childish, uneasy Japanese. She starts to be interested in shogi because of Naruto. Yaichi finds himself frequently overwhelmed by her cuteness, much to Ai's chagrin. She studies under the same master as Ayano. Not wanting to hurt Charlotte's feelings when he refused to switch and become her master, Yaichi offered to make her his"bride" instead. While this was successful in avoiding trauma from his rejection, her repeated mention of this"proposal" has caused some trouble for him. She seems to have an interest in Yaichi as seen in the anime.
