The Fearsome Witch Teaches in Another World: Volume 4

It’s the third and final day of the cultural festival at Fiddich
Academy, and everyone is excited for Aoi’s presentation, but for some
reason nobody seems interested in seeing her students’ lightning sorcery
demonstration. Knowing how hard they’ve worked, Aoi will need to act
fast to prevent their hard work from going to waste. However, another
problem awaits Aoi even after the cultural festival. There’s a student
who has become a shut-in, and it’s Headmaster Glen’s own grandson. Aoi’s
faced down haughty nobles, unruly royals, and powerful dragons, but
this could be her greatest challenge yet!
