Kunon the Sorcerer Can See, Vol. 5 (light novel)

Kunon has successfully made his magic-containing box a reality and moved up a grade in magic school. Now a second-year, he accompanies Professor Satori on her fieldwork and joins a group of teachers searching for a legendary plant deep in the school's underground maze. And of course, he immediately starts causing trouble.

Meanwhile, Gioelion's cousin joins the Advanced class as a first year and quickly becomes just as obsessed with magic as everyone else. It's shaping up to be another exciting year in Dirashik for Kunon!
