Sigh, I understand why the author might want to push Momo right now (she's been out of focus for a very long time before this arc), but I don't like it.
But I'll always be on board the spider ship. I've always liked her since she defied genre expectations in her first arc (Protagonist gets involved in pervert antics and is wrongly blamed for it? She helps him. Protagonist fantasizes about a date with her? They actually have one, a normal date where they share hobbies and a meal). And her return in chapters 47-55 remains the best arc in the whole series.
