@Operatix The author is doing a prologue. A set up to the story. The main story will begin in the next chapter. I know. We're used to the setup taking from a couple pages to most of a chapter rather than 2 full chapters, but this story looks like it needed those two chapters.
This scene was watered down a little from the [WN], the protag was a bit stronger when confronting the other reincarnaters and left a deeper impression, but the scene-
showing him save the other test subjects was refreshing.
