Death the Kid unleashing his Lines of Sanzu to connect them.
The Lines of Sanzu (ザ ライン オブ サンズ, Za Rain obu Sanzu) is a unique trait carried by grim reapers that serves as source of power.[1]
Cultural References[]
In Japanese Buddhism, the Sanzu River is the River of Three Crossings and the way to the afterlife. It is the Japanese equivalent of the River Styx. A person's soul crosses from the land of the living to the land of the dead by crossing one of three ways, depending on the weight of their sins, or karma: the good cross a bridge, the neither good nor bad cross through a shallows, and the bad cross through deep waters where vicious snakes swim.[2]
Overview[]
The Lines of Sanzu can vary in appearance on a grim reaper; it can appear as lines in the hair or the white break in the hair.[3] In their true form, they take the form of a white halo surrounding the head.[4] The Lines of Sanzu trait is a representation of a grim reaper's age; where a child's lines are incompletely while a fully mature reaper has either two complete lines connected or three lines connected.[1][3] As the child gets older, they are able to connect more of the lines. By the time they've connected the second lines, they're considered their own, independent grim reapers.[5]
Three Lines[]
Seemingly only a fully-realized grim reaper or their chosen heir can have three lines; within these lines also holds a wavelength of the parent that may be forfeited after the connection of the second line.[5] When the heir has connected all the Lines of Sanzu, the parent reaper is killed as a result[4] due to the fact that only one true grim reaper can exist at a time, the world not requiring an excessive amount of grim reapers.[6]
