Owari No Seraph: The War Wages On. Yuu X Rea...
The Owari No Seraph experiment had been stopped, leaving the Japanese Imperial Demon Army to go back to the drawing board. Even though it was stopped, there were still many complications. Krul Tepes was removed from power after being found out that she had a hand in the experimentation of the Owari No Seraph, leaving Ferid Bathroy to find a new target:
Half-ling princess, Mayu Shiranui.
As things progress, Yuuichiro Hyakuya goes under a horrifying transformation as his demon threatens to possess him, making it harder for his comrades to help him. As this happens, Mayu continues to struggle with her personal matters. Her mind becomes continuously clouded with memories that aren't even hers.
Who is Kimi, and what connection does she have with Mayu?
