Demonic Possession: Transformation

By merging with his blade, Samsara is able to transform into a demonic version of himself almost like an oni, with long, sharp teeth, short horns sticking out from his forehead, and razor-sharp claws.

Once Kishara and Samsara have merged together they are able to use their chakra releases in conjunction of one another. This allows Samsara to effectively cloak his entire body in the Steel Release: Impervious Armor technique; meanwhile Kishara channels his fire chakra through all of Samsara's body, turning that very steel shell into a powerful weapon. With Samsara's now steel skin acting as a form of attack (by basically being a hot iron to strike and burn victims with), and as a form of defense (since his skin would burn anyone that touches it). this allows him to attack his foes relentlessly, with little fear of the opponent striking back. Also while in this form, Samsara is able to perform techniques that originally only Kishara could use in battle, such as his Fire Release: Demon's Roar technique.
