The anime starts out where the main character likely dies in a house fire and wakes up as a 5 year old in medieval times. The beginning gave me Drop Dead Diva vibes, where the main character dies in a car crash and ends up in another woman's body, who had also just died. Anyways...
The first three episodes are great, it starts off as a magical fantasy anime where he learns that he has the ability to use magic and he trains with his master on how to use it. He has to be careful though, because if people find out he's a mage, he can overthrow his eldest brother and become the ruler of the land. After the first three episodes, the anime changes themes constantly. One episode comes across as a dating simulator, while another one will be like a fantasy/action anime and then the next one is like a cooking show. It's almost like this show has no idea what it wants to be.
Aside from the fact that he was originally from a technological world like Earth, there is almost nothing referenced about him being from another world. The biggest thing was him translating between yen and this worlds currency amount. There's almost no plot at all, he doesn't really talk about being from another world and there's nothing he's trying to do to at-least figure out how he magically went to another universe. It's barely and iseki anime at all.
He also seems to really like cooking, which is one of the only things that seems to actually stick with the plot-line.
One thing I will say, unlike most "Harem" type anime where all the girls have a crush on the guy. This anime takes it from a medieval perspective where people got married because it was a political statement, none of the girls seem to even be attracted to him and want to marry him for political status.
One of the weird things about this anime, I found myself assuming certain characters were bad guys, but they were good guys the whole time! It's confusing to me that they made some characters have the evil vibe when introduced, without actually being bad. I kept assuming some characters would backstab the hero, but they never did.
The anime has little to no conflict, there's no re-occuring issue that drives the characters goals aside from them wanting to be adventurers.
The last four episodes were pretty good, as they finally got to the plot!
