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

SOMETHING WICKED THIS WAY COMES…With their brief respite over, our heroes begin their fourth year at Kimberly Magic Academy. The school is still shaken by the “disappearance” of the philosopher Demitrio -- and a lineup of oddball new teachers arrives 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 caution. Meanwhile, Pete and Guy seek further bonds and strengths, hoping to match their comrades' accomplishments. But a mage's life is hell, and it will give them no solace. Once more, in the labyrinth's depths…someone will be consumed by the spell.
