I Have Death Note as Grimoire in Black Clover

"Do you wish for your own demise so much?" Light questioned coldly, clutching the pure white quill within his grasp. With a stroke of his hand, he inscribed the name of his target into his inky-black grimoire.

"I'll grant your desire," Light muttered, sealing the grimoire shut. Just forty seconds later, the distant individual succumbed to a sudden heart attack.

"That's not exactly his wish," remarked a peculiar figure known as a Shinigami.

This Shinigami assumed an unsettlingly humanoid form, characterized by an emaciated frame and a ghostly light-gray complexion with hints of blue. Tousled black hair contrasted starkly with his gaunt, blue-gray lips and razor-sharp teeth. His unnaturally elongated limbs sported rings on bony fingers, but his most striking feature was his large, round yellow eyes, which bore fiery red irises that seemed to pierce the shadows. Dark and eerie wings sprouted from his back.

"Quiet, Ryuk. No one solicited your opinion," Light retorted with a withering glare, maintaining his casual posture while clutching the grimoire.

[Note: The protagonist can be somewhat edgy at times, and he despises criminals for the harm they inflict on the innocent, although he is not as malevolent as Light Yagami.]
