Another little sketch, this time of Momoshiki and Kyo who I've sort of "introduced" here https://www.furaffinity.net/view/50352054/ .

As it says there, Kyo is Momoshiki's partner. He was born from a roleplay, as well as his relationship with the other and his design, including the kama, which looks like Boruto's but red (the design of the kama seal depends on the Otsutsuki and not on the vessel as far as I'm concerned).

Kyo is a misantrophe and spiteful person. He grew homeless in the streets of Konoha, and had the typical abusive upbringing, he was sold by his father to an abusive trafficker he developed a Stockholm Syndrom relationship with, getting abused for years until he finally made his escape. But his only option was to live in the streets. Young and hungry Kyo would get driven away with rocks or agressions whenever he tried to get food or sustenance. For all those reasons he resents his own species to an unbearable degree as he feels betrayed and wronged by it.

Due to the consequences that extreme neglect had in his health he's a shinobi academy dropout, he never became a ninja and can hardly control chakra. He's unable to perform any jutsu and his control of the kama is limited to clumsy telekinesis and telephatic communication with Momoshiki which the latter has to trigger himself.
They bonded over their mutual despise over "lower lifeforms" lol
