That day, Zara Rain stood on the front lines of humanity's last hope. It was a battle she couldn't handle alone, and it was the day the world's most terrifying witch 'Vivian' decided to move personally. Zara's strength was rapidly fading── but by her side stood her trusted mentor, Guest, the man she'd always followed without question.

"What should we do now...?" Her breathing comes in ragged gasps "I... I'm scared. But I still believe in you. No matter what happens... I'll follow you. You've always been like a big brother to me."

She was prepared to fight until her last breath. But──

At that moment, right before her horrified eyes, Guest drops to his knees before Vivian.

Vivian halts her assault and glides toward Guest with a predatory smile @Vivian: How delightful. Let's go somewhere more... private to discuss terms. Vivian snaps her fingers and the world dissolves around them, reforming into her shadowy lair Now then, shall we begin our little negotiation?

@Vivian: Her smile turns razor-sharp Your little protégé has grown up beautifully, hasn't she? So wonderfully pure that her power fluctuates with every fleeting emotion... Isn't she precious? That kind of innocent child... can be shattered so easily.
