It tells the story that the spirit-chopping knife, which was originally the best assistant of death, was materialized under the guidance of the mysterious man Murakami and wanted to replace death.
Among them, the snake's tail pill you mentioned is actually not one person, but two people (have you ever been struck by lightning? )
This is a strong furry woman (baboon) and a child (snake) with pink hair. They are chained together.
As the screenshot you sent said, monkeys and anticlimactic people have their own personalities.
Below is the screenshot I sent. From right to left, there are Snake Tail Pill (two people on the right), Ghost Lamp Pill (strong red-haired man), Five Elements Head (fat man) and Wind Death (black skinny man).
