First Among Toddlers. Book 5. Nanomachines, Kid!

The divine court of the very Virtue of Justice went well—I wasn’t burned to a crisp! Now I can return to my simple life as a magic first-grader, right? Yeah, sure. In the woods, monsters are waking up, wanting to find the ruler, while in the city something that calls itself Mr. Hyde is roaming about.

There’s nowhere to hide from danger. And who has to handle all this? Of course—the magical kid with nanomachines. To you! Give me a break!
