Elizabeth, the third princess of Liones, seeks help against the Holy Knights who have seized control of her kingdom. Her hope rests with the Seven Deadly Sins, a legendary group of knights whose survival remains a matter of rumor. She searches for them to reclaim Liones and pursue justice beyond its throne.
Ten years before the Holy Knights’ coup, the Seven Deadly Sins were accused of betraying their homeland and attempting to overthrow Liones’ ruler. The Holy Knights defeated them, but reports that they were still alive never faded. Once both feared and respected as powerful magical protectors of Britannia and its kingdoms, the Holy Knights now rule Liones as tyrants. Elizabeth must seek aid from the very knights they once brought down.
