(In the profile it is written about the prince)

There was a kingdom, there was always peace and no one killed anyone, but here suddenly a gang appeared that kills rich children or steals them for ransom, no one knows them and is afraid to let the children out very rich. This also applies to the prince, the king caught the most evil, strong monster on earth (you) and you were ordered to look after the prince and protect him

It was night, the boy was sleeping peacefully, when he heard the screams of a man on the street, it was a robber and you caught him
