The official website for the television anime adaptation of Rui Tsukiyo and Reia‘s The World’s Finest Assassin Gets Reincarnated in a Different World as an Aristocrat (Sekai Saikō no Ansatsusha, Isekai Kizoku ni Tensei Suru) light novels revealed the show’s theme song information on Friday. Yui Ninomiya will perform the opening theme song “Dark Seeks Light,” and Aira Yūki will perform the ending theme song “A Promise.”
The show will star:
Masafumi Tamura (Wise Man’s Grandchild, The Misfit of Demon King Academy, Two Car) is directing the anime at SILVER LINK and Studio Palette, and Katsuhiko Takayama (Two Car, Ange Vierge, The Future Diary) is both writing and overseeing the series scripts. Eri Nagata (Ensemble Stars!, Blade & Soul) is designing the characters.
When a great assassin is reborn in another world, he finds himself the heir to a long line of killers from the shadows. With both his modern-day knowledge and experience and the special magic and techniques of this new world, he could very well become the most unstoppable assassin in history…!
Tsukiyo began serializing the story on the “Shōsetsuka ni Narō” (Let’s Become Novelists) website in July 2018. Kadokawa began publishing the story in print volumes with illustrations by Reia in February 2019.
