The story follows Ichinomiya Shingo (25), an ordinary young businessman who wakes up in an unknown room and realizes to be in the body of a 5 year old boy named Wendelin, the eighth son of a poor noble family.
In the midst of a deadlocked situation and no administrative knowledge or land’s inheritance, he aims for his independence through his only talent he was blessed with, the talent of Magic.
Since the age of 12, Wendelin becomes a scholarship student at an adventurer school, and after the merit of solving a case, he gains a lot of success as a noble.
But that is just the beginning of a life manipulated by the aristocratic family.

The first three episodes feel like watching 3 different shows, so this is an interesting one. At first, Hachinan tte, Sore wa Nai deshou! appears as a generic harem isekai, starring a magician and his loyal, sexy party members; however, soon we learn this man reincarnated as a very poor young kid, like that was the whole point. Then, the second episode is a warm story about how this kid got his powers, thanks to a mysterious yet powerful sorcerer who just wanted a worthy disciple. Finally, the third episode takes us back to the future, with Well joining the Adventurers Academy.

Is it groundbreaking? Nope, by no means, yet this show manages to overcome its own flaws and actually make us want to keep watching it. It's not ecchi, it's not a generic shounen, and it certainly isn't the next big thing, but we have to say it turned out better than expected—although our expectations were very low. If you're sick of the isekai trend, you can just skip this anime and you won't be missing that much. If you like simple stories, though, maybe Hachinan tte, Sore wa Nai deshou! is not that bad after all.
