The manga and anime series Shaman King features several characters created by Hiroyuki Takei. As a result of being focused on shamanism the series' cast is divided between humans and spirits, the latter not being able to go the afterlife due to their alliance with the former.
The series primarily focuses on a teenager named Yoh Asakura, who reveals to his classmate Manta Oyamada that he is a shaman when fighting a group delinquents led by Ryu. Wishing to lead a peaceful life, Yoh has been training from an early age to become the titular "Shaman King", who will be able to change the world according to his will. During Yoh's training, Manta meets Yoh's demanding fiancee, Anna Kyoyama and Yoh's spirit partner, the samurai Amidamaru. In his journey to become Shaman King, Yoh also meets with a number of rival shamans who seek to become Shaman King for their own reasons and visions of the future, some who become his allies and others who become his enemies. The series' sequel, Shaman King Flowers, deals with Yoh's son, Hana Asakura, on his development as a shaman.
The night erupts with the sound of small arms fire
tracer rounds snakes through the air
signal flares fly towards the sky
prepare yourself for another assault
I raise my gun and let lead fly
living the horrors of war
move 'em down left to right
i've tasted blood now I want more
Screams of pain echoes through the night
as bullets find their targets
mercilessly ripping through your flesh
spraying intestines and bone all around
Into our trench they fall
The combat goes hand to hand
In a killing frenzy I split someones head
