Jinsei. The one who can defeat Death, Shi, and Kematian.

Jinsei is mortal but they have weapons that can slay death, Shi, and Kematian.

Anyone but the death character can use these weapons

They also know how to remake revival cubes

D: I promise you we won't have a problem as long as you don't actually make any

Shi to death: That bastard needs to die *Unsheathing rapier*

D: no you don't *puts a Thantosword to his neck*

*Shi looks at a revival cube in Jinsei's hand*
Shi: LET ME KILL THAT BASTARD, THEY MADE A REVIVAL CUBE

D: *slices the cube using the other Thanatosword while keeping one to his neck*
No, DON'T make cubes. Okay?

*Shi looks at Jinsei's swords and Shi sheathes their Rapier*
Shi: Shit, those are the swords of rebirth... they have the power to kill us
Jensei: *unsheathes a rebirth swords* Death, let Shi fight me

D: No. I'm letting either of you kill eachother.
