Shinengai

The Shinengai (深淵鎧, Literally Meaning: Abyss Armour) is a sentient armor piece, told to be an ancient artifact currently belonging to Kuro Kazuto.

Abilities
Tigzy, don't forget! Potential abilities:
 * Regens From Blood Like 7 Deadly Swords
 * Can minimize to user's core, their heart (the skin where the heart would be, not the heart itself) into a red core, and can be formed back into armor at will.
 * Can feed user chakra from past user's that it has absorbed it from.
 * Can absorb opponent's chakra if it comes in contact with the enemy.

Drawbacks:
 * If it is not accepting the user it drains chakra from them slowly, eventually killing them if it is not dealt with fast enough.
 * If it is not accepting the user it will slowly suffocate them, closing in on them, killing them.
