Komaki first appeared in chapter 2 of Symmetry Diamond, where she and her friends teased Oriko. Oriko warned her not to keep going out at night, lest she run into trouble.
Presumably Komaki and Kirika never fought or crossed paths in this timeline. Komaki and Oriko never seem to become friends in this timeline, however. It is ambiguous to whether or not Komaki is a magical girl in this timeline; her "going out at night" would suggest she was.
