Everything was fine...Not until this woman came to their life. She's known as an arrogant, doesn't respect her kings, good at fighting, and fearing nothing. She's a member of Assassination Group, became part of "Bloody Game" as her punishment from grave sins, and also almost died several times while doing her mission inside this school or Maximus University. This school contains killing, fighting, and bloody revenge. That's why it's called the ASSASSINATION SCHOOL.
