Technically speaking, Pollux is righte. Just because everything in the MGE setting has mana doesn’t mean something inserted from outside the MGE universe would suddenly get mana.

Though generally in Isekai or Waifu Invasion scenarios, I would assume that mana is an energy unknown to science for the sake of consistency (and ensuring mamono would be interested in men from this universe).
