Skyhigh Shinshou

Skyhigh Shinshou presents the stories of those souls who get to the Gate of Grudges. Izuko, keeper of the Gate of Grudges presents each soul with three choices: pass through the Gate of Grudges to heaven and be reborn, refuse to admit death and remain as a ghost on earth, or haunt and kill one person and then proceed to hell and eternal suffering. What does each soul choose and why?
