Return by Death

Return by Death is an ability in the anime Re:Zero, and was created by The Witch of Envy, or Satella and is exclusive to Nastuki Subaru. This ability allows one to return to a certain (randomly determined) point in time, and is normally an important event. This ability has caused Subaru much pain, and has even broken his mind and has gone insane. You can also never tell anyone about this ability, and if you do, you will be cut off and some people will immediately die. Subaru has suffered a lot, but thanks to his will power, he was able to strive forward to achieve his goal.
