The Super Dimension Fortress Macross: The Zentradi War Chronicles

(A view of Macross from the Zentradi perspective. Macross + the OTL timeline + Warhammer 40K + Gundam SEED + mecha battles.)

A young man from the modern era had his soul transported into the Macross universe. But he lost important memories during the transmigration. What's more, thanks to probability theory, he became a Zentradi female soldier in the 204th Female Main Fleet. She will go on to lead a cultural awakening, spark change, become a captain, and travel across multiple universes on adventures aboard the Resolute-class escort ship, searching for the meaning of her existence.
