5/5 stars
Before I start, I will say that the rating is biased simply because of how much I liked it. I can't say that the writing is the best or that it doesn't fall into Isekai tropes, but I ended up still loving it. This manga is about Seitarou Asao. He is a 73-year-old man who runs a tea field. Due to a god's mistake, he gets transported to another world in place of his grandson. He starts his second life 10 years younger as a 63-year-old man. There he lives a leisurely life with his wisdom and support magic.
The tropes it falls under aren't that bad. I was expecting truck-kun to show up, but instead, it seems as if he was just summoned. That was a nice change. A large portion of the manga has focused on a single town, but recently it has moved on to another. A common theme has been Seitarou introducing new inventions as well as protecting said towns from potential threats.
POSSIBLE SPOILERS AHEAD:
Although Seitarou is overpowered, he is humble about it. At first, people underestimate him, only to be impressed by his skills later. So far, the pace has been sort of slow. At the moment, there seems to be an end goal, but he has acquired a child that's also overpowered. I believe that they will play a bigger role in the future.
I would recommend this manga to other people. Including beginners, in terms of he Isekai manga, It is simple enough for them to understand the terminology used. It is also lighthearted and has good pacing. Since it's still ongoing, my review may be bound to change. If updates are slow on the manga, I will start the novel and review it as well.
