I want to find a story where the mc starts or is a kid. NO WEIRD PEDO STORIES! I like Picked up by the Protagonist of a Tormented, but wished the story stayed with the mc being a child longer and not having the whole romantic thing. I also don't really want a older person turning into a child. (Suggestions are welcome tho) I just mainly want a story about a young ignorant kid becoming OP. Age progression stories always make me happy. I want more than just yaoi ( actually prefer without it).
Maybe something like: Ascendance of a Bookworm Nigotta Hitomi no Lilianne (Um, Sorry) I’ve Been Reincarnated! The Man Picked up by the Gods Tensei Shite Inaka de Slowlife wo Okuritai No Fatigue Adventure Record of Reincarnated Aristocrat ~ The apostle of Gods who doesn’t know self-esteem~ Parallel World Pharmacy Youjo Senki
The Tale of the Ghost Eyes is actually quite good if you manage to read thorough first 20 chapters or so.
The Death Mage Who Doesn’t Want a Fourth Time ^this fits perfectly what you want i think he's like 10 years old now by the latest chapter or something correct me if I'm wrong
The Demon King’s Daughter is the World’s Strongest but a Shut-In! ~Shut Herself in an Abandoned Church to be Revered as the Goddess~ Manga wo Yomeru Ore ga Sekai Saikyou ~Yometachi to Sugosu Ki mama na Seikatsu~ Kuishinbo Elf <- she acts like a child though, and her friends are mainly her age. How about a dog ? lol. Woof Woof Story ~I Said I Wanted To Be A Rich Person’s Dog, Not A Fenrir!~
Coiling Dragon no reincarnation no starting as an adult long time spent as a "child" in the novel as well
