Mmmaybe?
This manga is implied to exist in the same universe as Kuroha’s other manga, which would mean magic, including time travelling talking animals and all sorts of shounen manga superpowers, are also canon in this setting. I could really see anything existing in this world, even if Christianity is also canon.
You could've done something with "boom shakalaka" for the pun. I dunno if it's less of a reach, all things considered, but at least the word she takes issue with is actually there...
She is an angel, but they arent under god orders, an angel can pray at god and receive god's help, but they cant see at god ... in the heaven she doesnt have a body xD, maybe same with god
