1x11 - High School Prodigies Have It Easy Even in Another World!

Conrad has plans for the Azure Brigade to rejoin the Rreyjagard Empire. However, Tsukasa predicted their betrayal and is now concocting a plan to counteract this. Meanwhile, an infectious new disease called Septicaemia has spread amongst the commoner. Keine is doing all she can to find a cure; however, there's a Penicillin shortage. To make matters worse, Count Serentius of the Medical Guild demands that Keine allow his Guild to sell opium to the sick. However, Keine refuses this. She instead makes a deal with Serentius that she'll cure the villages with coal. But if she fails, she will allow him to sell the addictive drug.
