Reign of the Seven Spellblades, Vol. 12 (light novel)

With their brief respite over, our heroes begin their fourth year at Kimberly Magic Academy. The school is still rocked by the "disappearance" of the philosopher, Demitrio-and a lineup of new oddball teachers arrive to fill in the gaps. Chief among them is the Great Sage Rod Farquois, a reversi. Concerned for his friends and certain that the new winds Farquois brings will lead to storms, Oliver urges everyone to exercise caution. Meanwhile, Pete and Guy seek new bonds and strengths, hoping to match their comrades. But a mage's life is hell, and it will not give them solace. Once more, this year, in the labyrinth's depths...someone will be consumed by the spell.
