@Zan00 Humina and Fumina are two possible romanizations for Fumina Hoshino's first name - Fumina is Hepburn (the default standard) and Humina is Kunrei. The gallery title and renaming system uses the cover/colophon for this, so mangakam is right and Humina is correct.
(Thanks for sharing and crosslinking to both galleries, by the way! Makes it much more convenient.)
