When the Castle Witch awakened in the 21st century, she found that her magic power was only 1% left, and her rent bill was piling up. In order to survive, the witch who once wiped out the city had to work in a convenience store, learn to use her mobile phone to scan QR codes to pay, and had to deal with the strange civil servants who called themselves the "Aura Recovery Administration". When she finally saved enough money to buy her first cup of milk tea, she unexpectedly discovered that the "magic" of this world was hidden in those daily routines that she had dismissed.
