Okashi na Tensei

In some sense an alternate version of this. The basic premise is exactly the same, but there are more similarities in tone, how life in the medieval era is depicted and how they go beyond a simple power fantasy. 

Both Mc are white head that will bring their previous life profession to another world. both anime follow the same naming scheme by doing pun with their names.  

I don't know for sure if it will develop like "Okashi na Tensei," but he gives me vibes of it. How so? First of all, we have the classic isekai scenario, where individuals regress from the modern world into a game, novel, or reincarnate into a world with magic and aristocracy. Both main characters are children and exhibit great talents from a very young age. Secondly, both main characters are learning and achieving milestones to become the next lord who will rule over the land of their family. In conclusion, I really think these two stories have some similarities; hope you like it. read more 

Did you watch Sweet Reincarnation and felt frustrated by the MC not baking sweets for more than 3 episodes even though the title says otherwise ? I present you Campfire Cooking in Another World with my Absurd Skill. The MC cooks at least once every episode if not twice, which makes it more fulfilling. The MC is also less courageous even though he's more adult appearance-wise (which makes him feel more human) and makes it apart from standard isekais. There's not a lot happaning, and it may feel a bit repetitive, but it's a good vibe show. 

Two fantasy isekai's where MCs are quite powerful but are very tactful and cunning in their strategizing throughout shows but have to go through some kind of war in order to gain what they desire. 

Similar feeling Isekai, also has OP child dragged into running a country whilst trying to fufill a alternate goal.
