Hory shit!!!OH MA GAWD
Oh, you know...How bad are we talking about?
Oh, you know...
"Blesses" him with mob-fu perception block without his knowledge, tries to forcefully use Alfana as a mortal vessel, merges/connects her body with his (in a non-sexual way, if you can believe it), vows to claim his soul for eternity once he's dead, almost runs out of patience and tries to reap his soul right there and then...
Basically, the most passionate, most dangerous and most unhinged yandere to be introduced. Which already says a lot considering what's already happened so far and what's coming down the track should the manga last that long.
Granted, there is an explanation for why she's unhinged. Kanata will explain it in the next chapter, but I'll sum it up here: she doesn't understand human standards of morality, so she does whatever she wants. So while she mostly leaves the world she's in charge of to it's own devices, she's also fully capable of both destroying it and recreating it should she want to. It's even noted by another goddess that she's extremely possessive and has a huge ego.
