Izure Shinwa no Ragnarok

Izure Shinwa no Ragnarok summary:

Once before Seven mythical G.o.ds appeared on Earth and their battle split the earth, tore the sky. 10 years after the battle, the calamity should have gone already.
However. A boy named s.h.i.+nsen Raika had his true little sister abducted by a G.o.d in the battle and was currently standing in the『Academy』on an artificial island in the distant seas.
Here, the night was called as after school time. During that time period, the 『G.o.ds’ Proxy War』 were being held by using Divinity-Compatible people for gaining the seat of the law of world (The supreme G.o.d).
On the first night, Raika was attacked by a Norse mythological G.o.d called Brynhildr. Facing death in front of himself he acquired the detestable power of G.o.ds, the power for revenge.
「Become my slave! Give me not just your hands and legs, but also your fingers, toes, and even your soul!」.
Absolute Domination, using that power from the devil eye of Balor, he tries to take back the world from G.o.ds control. A new mythical heroic saga of a devil eye-user person swearing to take revenge on G.o.ds begins now!
