Eison encounters yet another riddle of portals and by some miracle stays alive. With the help of the grandmaster Zereleus, he delivers another blow to drug dealers and demons—but they don’t stay in debt. And during his practice in the province, he will have to face all the treachery of the clan of the “Mighty.” Having agreed to give up active combat during their studies within the Academy’s territory, they eagerly await the chance to destroy Eison the moment he crosses its borders.
