God's Servant Space: Comparing with Gods with a Mortal Body!

Kikutaro, an elderly otaku, was accidentally hit by a truck and died. He was reborn in a parallel world where becoming a servant of God was the glory. Everyone in this world must enter the God's Servant Space when they turn 18 and take part in God's test. Those who pass the test will receive space rewards and become more powerful. Only the most powerful people are worthy of becoming God's servants and serving Him. But behind all this, is that really all there is to it? What is the relationship between God and space? Is the ultimate purpose of space just to give God a few more servants? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
