Jigen and the original monk both died after the two were incinerated. Jigen attempted to use Kawaki’s Kama to be reborn, but it turns out it was a shadow clone. He was defeated by Naruto and Kurama with their Byron mode but at the cost of Kurama’s life. Code’s White Kama is a non-vessel; therefore, Isshiki could not be reborn through Code. Before dying, Isshiki told Code that although his soul dissipated, Code would inherit the Otsutsuki Will and continue to strive for Godhood. However, the previous show is no stranger to suddenly making characters return after ‘dying.’ Hopefully, we could see more of Jiden in the near future.
