Eras, a genius wizard, together with Nikolai, an alumni from the School of Magic and a colleague, live by preventing 'calamities' large and small. Then one day, a series of runaway magic happens amongst the wizards and it causes chaos and confusion to the wizarding world. "They are definitely after me," says Eras as she looks for those who had caused the explosion. She makes decisions and moves haphazardly in order to save the world. In the end, she hurts all her colleagues in the process and, as a result, she receives the worst punishment for wizards: 'wiping away all of her memories'.Wizard Number Zero / 0 / The 0th Wizard / The Initial Archmage
