God Mazinger

While pursuing fugitives the Space Federation police officer Birdy Cephon Altera finds herself on Earth.

High schooler Hibiki is transported to a monster-filled fantasy world, where he possesses only non-combat skills. However, through key encounters, he discovers hidden powers and embarks on an epic adventure.

In ancient times, a great battle was waged between a master mage, Enno, and an evil demon goddess, Karuma. Enno didn't have the strength to defeat her alone and was forced to call upon Zenki, a powerful protector demon. After Karuma was defeated, Enno sealed Zenki away in a pillar located inside his temple. 1,200 years after this epic battle, Enno's descendant, Chiaki, unleashes her family's powers to summon Zenki.

The story revolves around Shu Ouma, a high school boy who inadvertently obtains an ability called "The Power of the Kings" that enables him to draw out items called "Voids" from other people. He is then thrown into the conflict between a resistance group called Funeral Parlor which aims to restore Japan's independence from a quasi-governmental organization known as the GHQ. In the process, Shu has to deal with the burden his ability puts on his shoulders and the horrific mystery of his past.
