An anime adaptation of the Chronicles of an Aristocrat Reborn in Another World light novels is set to premiere in Spring 2023. A key visual has been released.
EMT Squared and Magic Bus are producing the show.
Chronicles of an Aristocrat Reborn in Another World is written by Yashuu and illustrated by Nini (Yotsuba illustrated the first volume). The series, published under Hifumishobo’s Saga Forest label, began in 2017 and has six volumes as of December 2019. The story started off as a web novel on Shousetsuka ni Narou in 2016.

A Mag Garden-published manga adaptation by Nini began in 2018, while a Hifumishobo-published manga spin-off from Akane Sasaki began in 2020. Mo is credited with the original character designs for both. A manga anthology will be released on August 10.
Seven Seas Entertainment describes the Chronicles of an Aristocrat Reborn in Another World manga as:
Teenager Shiinya Kazuya died while saving young girls from an attacker, only to find himself reincarnated into a world of swords and magic. It was a dream come true! Though he remembers his life and knowledge of Earth, he is now Cain von Silford, the third son of an aristocrat. Being granted the protection of the gods on his fifth birthday turned out to be too much of a good thing for Cain. His stats and boosts are so powerful, he must hide his real abilities to climb the ranks of society as he descends into the darkest dungeons. The ultimate isekai adventure begins as a teen-turned-child is trapped in a beautiful kingdom he didn’t create, but might one day rule!
