"I don't think they will include her separate profile, in my opinion."

Anon-kun was referring to her character page on the haremking website. Not even Vali got one last season and he was significant for 1/2 the entire season. Rossweisse, despite being a future main character, gets 2-3 scenes in volumes 5 and 6 and she already has a character page.

Ishibumi himself stated he's satisfied with how the anime is being handled, so the option of squeezing 5-7 into 12 episodes is nonexistent. It's either the quite likely 5-7 2-cour or the best option to believe in 5-6 1-cour just in case to avoid being potentially disappointed.
