Date A Live Novel Volume 12 was written by Koushi Tachibana and features illustrations by Tsunako.

Shido has been steadily sealing away Spirits in his bid to let them all enjoy peaceful lives. Little does he know that there's such a thing as too much Spirit power! While an overabundance of it grants him superhuman strength, it also puts him in an incredible amount of danger! As luck would have it, turning him back to normal is a fairly simple process. Unfortunately, Shido has gone a little berserk and refuses to cooperate…unless, of course, the girls can woo him by the stroke of midnight!
