Bio: Once a professional medical nin, Kichigai was very famous at his time until he finally lost it because of repetitive and dull nature of his career, to recompensate for this dullness, Kichigai experimented on dozens of test subjects, mostly to see how chakra works, eventually he got tired of that too, to make his dull life more exciting, Kichigai went on to see if there is such a thing as immortality, he achieved that when he found a Jashin priest (Not Hidan), this has given him many opportunities to see how immortality works but unfortunately it was put to an end by the Kazekage, rather than executing Kichigai, the Kazekage (Gaara) simply exiled him, never to see him again or that's what he thinks.
