Kakamu (RBU)

Kakamu is a male Tekkui warrior from Nil'nara who was recruited into the New Order by Arc Keylana.

Description
Originally, Kakamu had dark red skin and yellow eyes. During the Arokazek's experiments on him, silver metal was grafted onto his body in several places, including his face, chest, legs and hands.

Following his perfection by Sefer Yetzirah with the Fruit of Life, Kakamu is a muscular humanoid with dark red skin and a gold-painted metal mask that is set deep into his face, seemingly having been fused to his flesh. The mask has an opening around the mouth with three open grilles on each cheek, a single grille on the forehead, and two 'spikes' that jut out from each side of the mask and wrap around the sides of Kakamu's head. His eyes are rectangular purple lights that shine through the two eyeholes of his mask and change shape in accordance with his mood. The chest area has also been painted gold with a New Order emblem imprinted on the left side. The rest of his body is similar to that of a human, except for the fact that around 50% of the total surface area has been replaced with a dark silver metal that covers most of his chest, groin, shoulders, upper arms, and legs, having been intertwined with his flesh. Although this metal almost looks like a kind of natural armor or shell, there are some parts of his body where the metal is integrated with machinery: his five-toed feet and ankles are exclusively mechanical, containing what appeared to be gears and pistons, along with his hands, part of his chest, and the backs of his thighs. His only visible weapon, a long metal spear with a two-pronged tip, is usually attached to his back via magnetism.

History
In his first appearance, Kakamu is seen tending to the wounds of his father, the Savant, which were sustained when trying to escape from an Arokazek vessel. Their conversation is interrupted by the ground starting to shake, signalling another Arokazek attack, so Kakamu takes Marasu to a nearby village to rally the others to defend it.
