Whether the trouble is big or small, Detective Monica and her mystery novel–obsessed familiar, Nero, will get to the bottom of it with help from their friends and a little unchanted magecraft!

Danger and Daring at the School Festival! Despite the threat uncovered at the chess competition, plans for the school festival and Felix’s big debut remain unchanged, making Monica’s mission to protect him more important than ever. Luckily, self-proclaimed villainess Isabelle and fellow sage Louis Miller are here to help. But then, on the morning of the festival, Monica learns there’s a cursed tool somewhere in the academy! Protecting the prince, retrieving a dangerous item, and maintaining her secret identity—can Monica make it through her first and only school festival in one piece?!

Has Monica’s undercover school life finally reached its end?

Winter vacation has finally arrived, and Monica is looking forward to a break from protecting the second prince.

Now she must escort Felix on a diplomatic mission to a neighboring country without him realizing she and Monica Norton are one and the same. Can she pull through, or will her body give out from the stress? And what new threat lies in wait for the prince at their destination...?

Out of the frying pan and into the fire!? Monika, the Silent Witch and one of the seven sages, has successfully infiltrated the academy and joined the student council.

Monica suspects Duke Clockford is somehow involved in the incident with the curse dragon, but she doesn't have solid evidence. With her left arm still suffering the aftereffects of the curse and her heart full of doubt about the second prince, she begins her second semester at Serendia. However, now the prince is on the lookout for someone with a wounded left arm, and there's a new transfer student at the academy—a notorious troublemaker from Minerva's who knows Monica's true identity. Meanwhile, the Starseer Witch warns that the Seven Sages will soon be down to six—could this ominous prediction have anything to do with Monica's troubles?
