Interstellar, the Lord accepts. It's not time travel, it's not rebirth, it's different from year to year, the CP is uncertain, the protagonist is dead, stupid, hot-tempered, under-pressured, under-trained, and in military uniform. The personality of the character you like will be added to the character, so please don't bring it in yourself. Let the plot travel through the boundless universe like a prolapsed wild horse.
