Vampire Knight + Hell Girl: Existing for You

When the Hell Girl no longer holds a grudge, when the Hell Girl breaks free from her predetermined path, and when she meets Zero Kiryu, who suffers under the weight of hatred, what sort of ripples will stir in this clear spring? Her job is to send grudges to hell. His job is to protect the Day Class students from vampires. She was supposed to have no heart, yet she fell in love. He hates vampires, yet has no choice but to coexist with them peacefully. The god of fate loves to play games, and the two who had no reason to cross paths find a chance to meet. I don't know what I exist for. Now that I'm no longer the Hell Girl, with no grudge to sustain me, why haven't I disappeared? Beneath the cherry tree, there is nothing in Ai Enma's scarlet eyes. If there's no reason to exist, then let searching be the reason. Zero Kiryu held out his hand, his silver hair fluttering in the wind, and then their hands clasped tightly together. Theme:
