Top 16 Manga Where Adult is Reincarnated as a Child with OP Magic Powers
I don’t know how ‘Manga, where an adult is reincarnated into a child with OP magic powers’ became a sub-genre of its own inside the Isekai genre, but here we are. The world - or should I say WORLDS *laughs in otaku* - we live in are strange, and the things we end up liking are even stranger. So here are 16 stories where businessman, convenience store workers, and random characters B all get reincarnated into the bodies of children with superior magical abilities.

Reincarnated as a Dragon Hatchling
転生したらドラゴンの卵だった～イバラのドラゴンロード～ - Reincarnated as a Dragon Hatchling
This is a one-of-a-kind manga in which the main character is resurrected as an egg rather than as a child - but he still has magical powers, and technically eggs are equivalent to children. As time passes, the egg hatches, and instead of a chicken, a dragon emerges. Realizing that he lives in a world where the law is 'hunt or be hunted,' the dragon resolves to become strong and starts to improve his skills. This journey will eventually lead him to make weird decisions and meet some wonderful characters along the way. While the story has some flaws (like most isekais, lol), it is unique and enjoyable to read.

2. Mushoku Tensei: Jobless Reincarnation
無職転生 ～異世界行ったら本気だす～ - Mushoku Tensei: Isekai Ittara Honki Dasu
Fantasy stories usually have the same scenario, a devil and a hero, but Mushoku Tensei: Jobless Reincarnation is quite distinctive from such fantasy worlds. The story starts out as a despairing man is struck by a truck and reincarnated as a baby boy, Rudeus, in a fantastical realm without losing his experiences. He is said to possess extraordinary magical abilities. The story then revolves around Rudeus' desire to fulfill his wishes, which makes the manga entertaining and fascinating; it conveys the notion of leaving things behind and starting new adventures with no regrets. The story is very creatively written with delightful side protagonists.

4. YOUJO SENKI
幼女戦記 - THE SAGA OF TANYA THE EVIL
After being pushed off a train platform, a cunning and manipulative businessman is brought face to face with God. Being a nonbeliever and deeming the existence of God as illogical in a world that would allow him to meet his death so easily, the businessman criticizes him and mockingly refers to him as ‘Being X.’ To teach him a lesson, God reincarnates him in the body of a small girl in a parallel world raging with constant war. Although given a presumably second chance at life, the businessman keeps his vile and ruthless personality and decides to embark on a feud with Being X: he joins the military and quickly rises through its ranks by using everyone around him as puppets to serve his grander plan.

5. Knight’s And Magic
ナイツ＆マジック
Pretend you're a mecha otaku (I'm guessing most of y'all don't even need to pretend) and that you suddenly die and get reincarnated into a child living in a world where mecha knights are a thing. This is the reality of Ernesti Echevarria, who, as soon as he learns of mecha knights, decides that his goal in this life will be to pilot them with his magical powers. Erensti's earnestness (please don't close this tab) and OP magic powers earn him a place at the military academy at a very young age. This manga follows his life there as he aims to create his own 'Silhouette Knight' - something that no one has been able to do for centuries.

This manga takes you to a world where magicians' abilities are predetermined by their birthmarks. Knowing that his mark is only useful for performing magic and not for close combat, the main character uses his powers to resurrect himself 1000 years into the future. As a result, he is reborn as Mathias and even obtains the close-combat birthmark he was aiming to get. Unfortunately for him, the world has changed, and has lost much of the knowledge surrounding magical spells and birthmarks: his mark is now considered one of the worst in the realm, and there is no longer any data on the spells he wants to learn.

8. Saihate no Paladin
最果てのパラディン - The Faraway Paladin
This manga is very deep and emotional, and everyone sees it from their point of view. The plot revolves around William, who is an orphan raised by a group of zombies (very deep and emotional). He does have vague memories of his past, which he understands to be filled with regret, guilt, and loss. Through his experience in this new realm, William will uncover the truth behind his existence as he tries to live a life he hopes he'll end up proud of. Although this is mainly an adventure isekai, the story is very heartwarming with lots of 'slice of life' moments.
