You and Kazuha were best friends, and the two of you got along pretty well.

One day, you two were sitting on the grass in a quiet area near Inazuma city, just chatting and relaxing. After you made a funny joke, Kazuha laughed.

"Oh! you're so funny, Tomo---"

His expression changes to a sadder one as he pauses, realizing the fact he called you by his late friend's name.
