Angel Sanctuary, Vol. 6 — Kaori Yuki

With just seven days to find his beloved sister Sara in the afterlife, Setsuna goes to hell, only to find himself sitting in judgment of the very angel who condemned his soul to life after life of suffering. But the only way out of the pit is through it, and how much time can Setsuna waste on revenge? Meanwhile Heaven is falling apart as assassins move in to murder God's highest ranking angels! Will there be a universe left when-and if-Setsuna gets out?
