A nurse who came to the Land of the Dead from modern Japan and travels with Scarlet. She joined the adventure without realizing she died instantly after being stabbed in the modern world (meaning she cannot return to life). Crossing through time and space to this world, Haziri is a selfless and kind person who helps both friend and foe. Although she initially clashes with Scarlet, she eventually accompanies her on her journey, helping her find the meaning of life beyond revenge. Ultimately, they move past personal goals like vengeance to find the meaning of life amidst the chaos of life and death, adventuring together toward the 'End of the World' to prove their reason for existence.

A cold-blooded king who killed his brother, King Hamlet (Scarlet's father), to seize power. For some reason, he fell into the Land of the Dead and now targets Scarlet's life. Since he died instantly from poisoning, he cannot be reincarnated. At the End of the World, there is a massive mountain, and at its summit lies a staircase leading to the Endless Place. There, a large sealed door exists, which only those whose bodies are still technically alive in the living world can pass through to be reincarnated (a fact only Claudius knows).

A close aide to Claudius who leads the knights. He targets Scarlet's life in the Land of the Dead (arriving there after an instant death). In the end, he ultimately helps Princess Scarlet.
