No one knows how the pampered and wicked Erin Lisus suddenly becomes a top swordsman at Atenz Academy. That's because they don't realize that Erin was actually transported to the past after being killed by her stepmother and was reborn into different worlds. Now, with her past experience as a swordmaster, Erin's out to get revenge and rescue her allies from her stepmother's grasp. But with foes at every corner, can Erin save her loved ones? Or will her reason to wield the sword vanish with them? (Source: Tapas)
