"It seems that the unexpected isn't limited to just one instance," Orochimaru was very satisfied, "Kimimaro, how do you feel now?"
"Lord Orochimaru, I feel as if I have transcended the mortal realm and can fly freely; furthermore, the chakra within me isn't as dormant as before and can be utilized at will." As he spoke, Kimimaro raised his hand and a mass of chakra gathered, transforming into fire, water, earth, lightning, wind, and then into flowers, birds, and fishballs, morphing as he desired.
But chakra, after all, is just chakra. The things transformed from it are not real, just ephemeral illusions.
Regardless, Orochimaru was ecstatic.
Indeed!
Chakra is the thing of the Otsutsuki Clan, which they can use at will without any fetters, while humans from the ninja world need to refine it, to form seals.
"Teacher Orochimaru, is he an Otsutsuki now?" Yakushi Kabuto asked curiously.
