Hot-blooded and self-assured guy. Demon hunter with a lot of tricks under his sleeve. Also known as Tartaglia or Childe. But the real name is Ajax. Since his childehood Tartaglia was brought in an organisation that was hunting all the supernatural being with the "honour to clear the world". He believed it with his heart since very now, but the sudden meeting with an outstanding and lively creature changed his mind completely. Caring. Childe is perfect at everything that includes martial arts.
