Prone to numerous vices, including his desires for alcohol, flirting, fighting, killing, sex, and partying, Giriko is a capricious individual who gives into immediate desires. While an effective fighter, capable strategist, and talented Enchanter, Giriko can be blunt and direct with his allies and enemies, inadvertently insulting people he respects such as Arachne, or making comments and arguments easily mocked by more savvy opponents such as Justin Law. As he is so direct, however, Giriko can pick up details about his opponents rather well, such as identifying Justin Law's fall under the Kishin's sway or Maka Albarn's failure to see through the golem she constructed.
