Troubled by his overwhelming strength, the mage too strong for the world chooses to give up on his current life and decides to be reborn a thousand years into the future. However, he is greeted by a world in which the knowledge and usage of magic have regressed drastically, leaving his ambitions of finding someone stronger than him shattered. Going by his new name Kurt, the mage encounters a girl called Lala, who encourages him to enroll at the royal capital's magic academy, easily achieved as he maintains the powers he had accumulated in his past life. Meeting new friends and foes there, the world he finds himself in has new challenges in store, but this second life may just offer the enjoyment the cheat mage Kurt desperately pursues! 1446d

Read until chapter 13, let's just say the overall quality of this manga remains poor, very much deserving of its 5/10 score.
When I dropped it a while ago and got back into this manga, I got this story mixed up with some others. Some other manga like "Shijou Saikyou no Daimaou, Murabito A ni Tensei suru" is one of them, why? It's all about a generic demon lord/strongest mage that goes to the good-for-nothing world in the future, where humans have somehow rebuilt a kingdom surrounded by your typical isekai city walls, and magic somehow always gets weaker.
Usually, if not all of them, usually start out small with only 2 characters of the harem, and if these manga are not on the chopping block, they start introducing the rest of the stereotypical harem characters.
Overall, even reaching this chapter, nothing stands out, although there is nothing to talk negatively about it, unlike the other manga I mentioned like with their poor pacing, the overall lack of compelling concepts just adds to the dull plot this manga has. Just read other more interesting harems, there are way better selections.
and is the last one the only translator working in this manga ? this guy uses unedited google translate
