I Will Open up the Kingdom of Light!

Hello, I'm Akivili Hee hee I'm lying to you, I'm Aha Hahahahaha! … In the world of eternal night, a carriage fell from space. Hello, my name is Akivili. The young man who walked out of the carriage introduced himself. Let me open up this new world! But only a handful of people knew that Akivelli had died long ago. Of course it doesn't matter. The important thing is that this is a world shrouded in eternal night. In the world where the sun disappears, monsters are born. So shouldn't this be an Ultraman fanfic? The system should also be the Ultraman system. Why Stardome Rail System? ! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
