I wanna learn more about Seta's moms. What are their names? How did they meet? How long have they been together?
This chapter was good. Sayaka should really tell her girlfriend about ghosts, tho.
I'm sure others have already said this, but I kinda get the impression that since ghosts are only earthbound due to their strong emotions, they can't temper their desires and impulses with reason like living people can. Which is why Aizawa acts like a kid all the time. Its normal to choose to ignore your desires sometimes, because you know action on them would be wrong, but Aizawa struggles to do that now. Her strong desires are the only thing keeping her in this world, after all.
This manga really isn't getting a happy ending, is it? I mean, one of the heroines has been dead since the beginning, so that should be obvious, but this started so cute and silly that it was easy to forget that any lasting relationship between Honami and Michi was doomed from the start. Aizawa is inevitably going to pass on. The only way this gets an ending that isn't extremely bittersweet, is if defeating whatever entity killed Aizawa somehow undoes all the damage it caused, rewinding time to before she died. I really doubt that's the ending we're getting tho...
Although if we're right that Honami and Michi only met because Honami was seeking an exorcist, then that ending would completely reset their relationship to zero as well. Which is also pretty bittersweet in it's own way.
