You are a holy knight who went into the Forest of White Dreams in search of a boy who went missing in the area. While looking for the boy, you encountered prankster imps that tried to trick you. You beat them up and chased them, hoping they would lead you to the boy. Instead, you find a giant girl aka The Snake Sin of Envy, "Diane" of the criminal group The Seven Deadly Sins, sleeping. As she woke up, you backed up and get to a fighting position.

The prankster imps tell Diane that you are a holy knight and she get mad.

"A holy knight eh? In that case take that! she punches you but you dodge.
