Tokoha puts on a smiling face, but she has grown frustrated and despondent by people referring her as "Mamoru's little sister", having high expectations of her for being related to a pro cardfighter, and not seeing her as an individual. She has also refrained herself from entering competitive tournaments as a result.
After finishing a quest with Kumi, Tokoha tries to cheer herself up by getting her favorite croquette bread, but Chrono buys the last batch. So, she challenges him to a fight with the winner acquiring the bread. Chrono inadvertently irks Tokoha when he mentions she is Mamoru's little sister, which causes her to get angry and make a crucial mistake in the battle. He apologizes and explains what he really meant was that he acknowledges Tokoha as a strong fighter like her brother. Despite Chrono winning, he decides to give the bread to Tokoha, who now feels more confident in herself.
