The man disappeared down the street.
The old man lowered his head, looked at the compressed biscuits in his hand, and suddenly shuddered.
He remembered a legend that had been circulating recently - in the ruined city in the north, there appeared a Shura who specialized in killing the "Holy Mother". He kills both zombies and robbers, especially those who stand on the moral high ground and kill innocent people in the name of kindness.
People call him "Mercy Shura".
Because he said something: "Shura wields his sword, and the blade is full of compassion; King Kong's angry eyes are full of compassion."
Every "Holy Mother", "Green Tea", and "Idiot" who died under his sword would leave this note: "Failure to eradicate evil is to help evil."
