Shaman king: Flowers 6.

Death Zero
After losing a fight against his father Yoh, Hana is again damned to hell—this time to the war-era island of Peleliu. Hana encounters a kindred spirit in Sakurai, Second Lieutenant of the Japanese Navy whose alter ego is the flame-skulled grim reaper Death Zero. Meanwhile, Yohsuke and YVS continue their attack on Team Hao in the Flower of Maize, prompting a brutal war. Can Hana escape his circle of hell, and return home to the world of the living?
