Advanced magic and advanced science are basically indistinguishable from one another. It's just the explanation that makes them different. How does that power suit work? Science answer: "Oh it has a fusion reactor." Magic Answer: "Oh it has a powerful magical core." How does that gattling gun work? "Gunpowder." "Kinetic energy spell." How does that plasma rifle work. "Oh it has a plasma cell that holds inert ammunition before its primed and fired." "Oh it's enchanted with a high-class flame spell that requires an external source of mana to activate. Which is supplied by its "battery" packs." How is Kuro so strong? "Nanomachines. And copious genetic/bio-engineering." "He's an oni." Seriously.
