Those kids should just travel around the world giving names to all the beasts and monsters they encounter. That consumes a huge amount of energy, after all. Of course those upgraded monsters would then decimate the human nations, probably, but not everyone can win in life, right?
It's good to see the manga doing better than the novel. The translation or dialogue was very poor in the source material and it's certainly leveled it self off, things are still a little "generic isekai"-ish but they're better than the average one at this point.
I would really appreciate it if the author, at some point in future, resurrects Shizu. Like, rimuru be able to do that after gaining some kind of ability.

But we see the Oni. When they first appeared, they were all about revenge on the orcs. They can't skip orc arc if they're introducing them.
