Thursday of Shock - S1.E9

Hibiki awakens on Thursday and to his surprise, finds Alcor waiting in his quarters. Over coffee they casually discuss the state of affairs. Hibiki, now believing that Alcor isn't a threat, gives him sanctuary in his JP's quarters, with a promise that he not reveal himself and what he actually is to anyone, for fear of creating a panic within JP's. Just then, Daichi and Io enter Hibiki's quarters and find Alcor, much to their shock. Although, Hibiki is forced to confide in them about Alcor's nature. Later that day, Airi and Hinako are selected by Makoto and Fumi to challenge the next Septentrione. Much to Hibiki's reluctance to let them fight, Makoto explains that the Septentrione: Alioth is scheduled to manifest in the Earth's Ionosphere, and hence, specialized long ranged demons that only Hinako and Airi can summon, stand any chance of attacking it.
