I Transmigrated into Oregairu, and Now I'm in Stalingrad?

The Too Long, Didn't Read Version: This is an infinite-world novel about a transmigrator forced to get caught up in other worlds. (The first world is a fanfic of the German anti-war film Generation War.)

Original Version: Yoshiteru Zaimokuza is a transmigrator who gets thrown onto the most brutal battlefield in human history after enjoying only a few days of peaceful everyday life. But after barely crawling out of hell, he discovers that ordinary life has slipped away from him without his noticing. He can never fit into the normal world again, and in one otherworld after another, only battle is eternal.

This is an infinite-world story, not an invincible-protagonist story. World sequence: Oregairu (main world) -> Eastern Front of World War II (completed) -> Main World 2 -> Warcraft.

A new writer with a new book. My first small goal is to write 300,000 characters (completed), and the next goal is one million.
