"I must become...stronger."
— Moonstone —

Moonstone (月長石) is a Twin Blade who joins Kite's party in .hack//Mutation. He is obsessed with becoming stronger in both The World and in real life.



Moonstone has light blue hair and an orange-red headband covering his eyes. Behind the hair covering his face, and under his headband, there is a purple tatoo stretching diagonally across his face. He wears red shoulder pads, but no shirt. He has black pants with the knees cut open. He wears sandals on both feet, but his right foot is completely tatooed purple.


Moonstone is the strong silent type to an extreme degree. When he does speak in a complete sentence, it'll be short.


Basic Info

Moonstone works out and trains constantly. He doesn't specify why. Perhaps he is a personal trainer at a gym, or a professional body builder. The reasons for his intense training are never made clear. In his emails, Moonstone mentions encountering a puppy that begins to follow him while he jogs. At first, he calls it annoying, but eventually becomes attached to the dog, and starts worrying when he doesn't see it. In the end, he locates the dog's owner, and changes his jogging route to see the puppy everyday.

Moonstone does not play a significant role in the story. Instead, his story takes place in the sidequests that he is involved in. Moonstone joins the party in a strange way. While going to different fields to meet Nuke Usagimaru, Rachel, and Gardenia, Kite encounters Moonstone in all three dungeons, at which point Moonstone would disappear. After seeing him three times, Moonstone sent an email to Kite containing a field name and his Member Address. After teaming up with Moonstone and going to the field, Kite found out it was Moonstone's intention to eliminate every single monster in the dungeon.

Later, he invites Kite along to help him retrieve an item called the Moon Knife from a dungeon. Then he invites Kite to a field supposedly to level up. Once there, they meet a girl named Aquamarine in the dungeon. She wants something from the bottom floor, and Moonstone gets Kite to help him get it for her. Once they've given the item to Aquamarine and she leaves, Kite hints at Moonstone's infatuation with her. In return for his silence on the matter, Moonstone gives Kite a Twin Blade weapon called "Prepare to Die".

Like everyone else, Moonstone was present for the final battle with Morganna.


  • Moonstone gives Kite his Member Address by mail after Kite accomplishes Nuke, Rachel, and Gardenia's missions.
  • Moonstone first joins Kite at level 30 with a level 11 weapon called Grizzly.
