Gemstone Release: Tourmaline Fist

The user combines Earth Release: Earth Spear and Crystal Release: Crystal Armor together. The result is a crystalline, pink shell with extraordinary hardness and durability. Its defensive properties are remarkable, but its sole user, Torumarin Houseki, uses it to greatly enhance the destructive power of her taijutsu. While never shown in the RP, it is implied that hits from this jutsu are easily capable of maiming and crushing victims to death.

Trivia

 * During the Second Stone and Leaf War, Marin was shown having killed a Iwa scout. The scout was seen having been brutally smashed in due to this jutsu.
