From my knowledge of LNs… The majority are: Isekais, in less technically advance eras, involve lots of cooking, the MC is OP and there a school somewhere.

Theory -

The MC is a deer, he was one of santas reindeer but after being hit by truck-kun he is reincarnated to another world as an OP deer. He starts with max stats with the skill limit breaker to allow him to transcend the gods. The world is in the pre historic era and after attending the most prestigious school (at which he was bullied) he and his human friends set of to save the world from the demon Lord. They travel while eating dinosaur meat (which spans 10 pages each time they eat) until he one punches the demon Lord so hard the demon Lord gets reincarnated into the MCs original world. At which point he is crowned the deer king!
