Alternate World might be a fantasy game with gods, goddesses, and demons alike existing in one place, but that doesn't mean religion does not exist here. And I can exactly tell why Tina is worried about the wish-granting "heart". Since it belongs to the Primordial Sea God, can the wish still be granted if it was made by an insect person and not merfolk?
That is the biggest question right now for her and I can understand her hesitations. But there is no point worrying now. If she can't deal with Lemis, when push comes to shove, I will be the one who will finish the job. I know I am not the one supposed to finish everything and even though I killed Lemis's brother, Remis, I should at least give Tina the leverage to kill and end everything, whether she is Alexandria or she is Lifera.
She went down from the tree and observed me gutting all of the Fanged Rabbits.
