Rant Warning
Momoha (the slovenly, drunkard, morally corrupt ethics teacher living in a tent) gets on my nerves. Very much the least enjoyable character in my opinion and contributing little in comedy, even though the dichotomy of her being an ethics teacher yet always acting immorally is supposed to be funny, despite that she preaches to not be like her. Her dynamic as a girlfriend is severely hampered by all this as there is little to actually love about her in my point of view.
I kind if hope we get a sort of intervention and rehabilitation arc for her to fix her up a bit. Get her into an apartment, get her to alcoholics counseling, and manage her gambling and sexual harassment (though that could apply to Hakari as well).
While by the end it would basically devalue her intended comedic use, which as I stated I didn't find very amusing anyway, the emotional journey that could be experienced in a rehab arc would add more value to her overall than continuing with her current depiction for the rest of the manga.
