Game of Familia, Vol. 5 (manga)

After their victory in Daba, troubling news reaches the Hatsushimas. Deadmales have been reported inland, far from the fortress meant to hold them off. The message is clear—Lyknell, the land of magic, has progressed its heinous experiments on deadmale militarization. What must be done is clearer—infiltrate Lyknell! Following Hunan’s strategy, Sasae and his sisters prepare to enroll in the Lyknell magic academy…but how will they fare in the classroom of the continent’s strongest mage, Ordo Seeka? And what of the mysterious and beautiful girl he uses as his guinea pig?
