Torkoal functions much like a furnace, and based on the commentary mentioning Demon King (whose fan-translated name happens to be "Furnace Core Finale") I assume the connection made here between a certain bnuuy and fire tortoise is a very favorable estrus environment.

I think in this case this is a mistranslation - the bunny people in Arknights are called Cautus, which is also spelled コータス in the JP text. Adjusting since there's nothing pointing this to the Pokemon specifically.
