"Kyokou Suiri (In/Spectre)" TV anime has been announced!! Synopsis

Kyokou Suiri is a unique anomaly in the world of anime. It rejects the action-packed, fast-paced detective thrillers in favor of a slow-burning intellectual drama where the battle takes place in a chatroom and the weapons are words. Whether you find the long speeches on logic to be a bore or a bliss, there is no denying the originality of the concept. With a manga series that is still ongoing and two successful anime seasons under its belt, Kyokou Suiri has secured its place as a modern cult classic for fans of Japanese folklore and unconventional mysteries. It reminds us that in a world full of gods and monsters, the scariest thing might just be a teenage girl with a WiFi connection and a fictional theory to prove.
