Ms. Diviner: The Prodigal Daughter's Return - Chapter 14 - acts cute after getting a bargain

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

“Look, I don’t need to be the strongest — I just need to be slightly stronger than the guy trying to kill me.”---Zayn Eldrake was nothing more than a nameless extra in the grand tale of summoned heroes — a disposable swordsman in the legendary Hero of Light’s party, fated to die in an early battle against the monsters of the Apocalypse.But when he awakens in this doomed body with memories of his past life, he refuses to meet the same pathetic end.He knows the story.

Reborn as Rasmus Blackheart, a disgraced young noble, his task is clear: unleash chaos and topple the order of Neva, just as he did on Earth. But the Devil has added a twist to the game—he’ll serve as Rasmus’s companion, not as a guide but as a mischievous, manipulative force, more likely to hinder than help.Navigating a world brimming with intrigue and divine interference, Rasmus must survive, scheme, and rise from ruin to reshape Neva in his image. Will his cunning be enough to outwit his foes—and his so-called ally—or will this chaotic partnership lead to his downfall?
