Manji is the protagonist of the Japanese manga series Blade of the Immortal. In the story, he's known infamously both as the "Hundred Man Killer," for the number of men he's killed by the beginning of the series, and "Mister Twelve Blades" for the number of weapons he carries. He is most easily identified by the manji symbol he wears from which he derives his name and the scars across his face, and as the title of the manga implies, he's been given immortality by the means of the Kessen-chu, which prevent him (for the most part) from dying.

Alucard (アーカード, Ākādo?) is a fictional character and the protagonist in the Hellsing manga and anime series created by Kouta Hirano. He is devoted to his master, Integra Hellsing, and gets along well with the butler Walter C. Dornez. He also has feelings of affection towards his fledgling, Seras Victoria.
