Four different girls. Four different lives. They're all on the same mission: to protect their world from demonic forces who threaten their homeland. "Then what are we waiting for? Let's go kill us a demon!" Kasai is fiery and carefree. But she holds a deadly secret - literally - about her katana, and keeping it from her friends won't be easy. "It's disrespectful and uncivilized to disturb someone who is peacefully drinking their tea." Aya is the sensible one; she runs from a life of betrayal and sadness, mix-ups and mistakes. She hides it all in hopes of becoming someone new. But she can never fully hide from the past. "Blueberry muffins!" Yuri is always happy - the jokester of the group. But she is in secret royal trouble her friends don't have a clue about, and has a side no one has seen before hidden deep within her heart. "I will keep my promise." Hikari is new to demonslaying. She . . . isn't Hikari. But they can't know that now. Together they stand as Surieyazu, the most famous and revered demonslayers in all of Sekai. In a fight for humanity, they will need the help of everyone they can get - old masters and new teachers, runaways, nemeses, traitors, and the dead. The Sureiyazu must find their place in the world. An adventure filled with fantasy, fighting, friendship, and love. I hope you enjoy.
