Karma (楔, Kāma) is a seal bestowed by members of the Ōtsutsuki Clan that takes the form of a four-point
Also Karma acts as an Ōtsutsuki backup file for their consciousness. Upon death, an Ōtsutsuki can resurrect themselves using the karma seal they put on a vessel. The seal will then rewrite someone's genetic pattern, turning Them Into A Ōtsutsuki. In The Anime When Momoshiki Ōtsutsuki implanted karma in order to revive him self using Boruto's body as vessel. Kawaki had his own karma, implanted upon him by Isshiki Ōtsutsuki. Upon using a karma seal for resurrections, any other karma seals put on other vessels by a singular Ōtsutsuki will disappear.
