The Unsuitable One at the Demon King Academy Transmigrates to Re:Zero − Starting Life in Another World
### Worldbuilding
- **A dual-transmigration system**: Anos Voldigoad transmigrates from the world of The Misfit of Demon King Academy to the world of Re:Zero. He retains all his former powers and memories as the Demon King, only to discover that this world's rules of magic are completely different.
- **Clashing abilities**: The power of the Demon King of Tyranny collides with the rules governing the Return by Death ability. As a result, every time Anos dies, it sends ripples through time and space that reach far beyond Subaru Natsuki's individual timeline.
- **A reshaped balance of power**: Alongside Re:Zero's four existing factions (the Royal Faction, the Merchant Alliance, the Witch Cult, and the Demi-Human Tribes), a new faction emerges: the "Demon King's Remnants," a mysterious organization that follows the legends of Anos's previous life.
### Synopsis
- **An abnormal arrival**: While investigating a magical anomaly, Anos is forcibly transported to the royal capital of Lugunica, where he discovers that it is under attack by the Witch Cult. He casually wipes out the attackers, but this causes a rift in time and space.
- **Fates converge**: While rescuing Emilia, Anos witnesses Subaru Natsuki's Return by Death for the first time. The powers of the two transmigrators resonate, triggering violent upheaval in the world's laws.
- **A shattered understanding**: Puck discovers that Anos possesses a mana reserve surpassing that of the Witch of Envy, while Anos notices traces of history that have been deliberately altered in this world.
- **The mystery of his identity**: The Witch Cultists call Anos the "Lost Archbishop of Sin," while the Kingdom's knights discover his connection to the "Void" from 400 years ago
