Two guests who came from nowhere unexpectedly got involved in the Holy Grail War.
A person only has the past, and even if it is a dark wasteland filled with endless piles of discarded dolls, he cannot abandon it.

The background is the Five Wars, with the participation of original protagonists
Dual male protagonist setting: Zero and Ye Guang (these two are not CP)
The protagonist of this article is Zero, and Ye Guang is the protagonist of another/several articles in this series (if you can really write it...)
1V1, HE
Note: The names of Zero and Luminous may sound weird, but there is a clear reason for them. So please forgive me (mainly because my name is useless...)
