X-ray
noun
レントゲン comes from the German word "Röntgen" meaning X-ray, named after their inventor Wilhelm Conrad Röntgen. If that’s news to you, here’s a mnemonic to help you remember: You’re planning to rent a Genji (レントゲン), but you ask Genji to get an X-ray first, just to make sure he’s in good health before signing the rental contract.
