The faded person who shuttles between the everyday and the extraordinary

He traveled through another world and became an immortal fader. As the last believer, he was chosen by God to travel across the world again, just to seek the power of the other world to become the King of Elden and save his fragmented hometown.
The thrilling heroic epic begins! ....that's how it should be.
My companion from another world is actually the Gray Witch?I also became Shinomiya Kaguya’s half-brother?Do you have to study hard in order not to lose face to the Shinomiya family?
How could he do that kind of thing!Something is wrong with this development!I am a fader!I have to fight for the world!
I escaped from Shinomiya's house and school...I met a rock girl. Girls who play rock and roll seem to be quite interesting?
Ah, no, I have to save the world!
...But it’s too weak now. As expected, it will take a while to become stronger!
With this thought, day after day passed like this, until one day... the doll and god that was regarded as a handicraft finally couldn't hold it back, and simply and rudely threw him to a new world.
——The story that shuttles between everyday and extraordinary, the chapter of war and death has officially begun.

(PS: The early stage is daily life, and then there is infinite flow. The daily world is the main world that can be returned)
