Sword Art Online, as reimagined by famed fantasy author Soitiro Watase! Asuka Empire. A Japanese-style VRMMO created by Akihiko Kayaba from a VR engine entitled “The Seed”—a game once played by Yuuki, Ran, and Merida of the Sleeping Knights that hides many stories. Two young women—warrior priestess Nayuta and ninja Koyomi, who became friends in-game—come across a mysterious priest named Yanagi. The elderly man tells them that he's looking for a detective to solve a riddle with a one-million-yen reward. The girls are shocked by the outlandish sum for this peculiar request, and then they meet an equally peculiar young man, who claims to be able to do this job as well as any other detective. With all his stat points invested in Luck, the man is useless in battle, but he does still seem to have some tricks up his sleeve, like that unbeatable drop rate for rare items... The mystery unfolds as two young girls and their dubious detective partner try to solve the case in this cutting-edge VRMMO world! (Source: Yen Press)
