I guess, Ish will encounter those girls next, and judging by the last panel he will be also cursed or hurt, so they should help a pretty looking injured gal, all-girl party? sounds fun~
Wait is it already known how they increase in number?
What if they are humans turned into goblins because of a curse and that girl Ish killed last time with the ring is part of a group finding a way to get rid of goblins by turning them back to humans.
What if the people they killed turn into goblins and that's why they increase in number even if they have no reproductive organs.
I still find it odd that both of the goblins turned humans became women its a coincidence if its just once but there being two is raises questions the other goblin seem to know Ish as well and she has been in human form for a long time enough to learn how to be a doctor and be known.
Man so many questions that needs answering. I need to go back to gooning.
