Two women can't produce offspring unless sperm is shared. However, if there IS a way to produce offspring between two women in the touhou universe, please enlighten me.

A fair amount of the Touhou fandom multiverse allows het as well. The series is flexible enough to qualify as "bi" depending on the artist. If anything, the Pokemon fandom makes Touhou look straight.
