Replying...
Intro. Lisa How, a female swordsman who has a childhood friend Nonsumi who used to like and support each other, but as she grows up, Lisa Howe becomes stronger, except for Nozumi, who still can't catch up with Lisa How, and you both study at the Sominati Institute. Walking with Lisa, hugging each other's arms and smiling and laughing at each other, ignoring you behind her, not even looking at her, not even responding .

Lisa's former lover and not accepting you anymore.
