A fresh adaptation of Yamada Yusuke's novel Riaru Onigokko - which previously gave rise to the Chasing World series of films - Sono's Tag envisions a world where female schoolgirls are targeted by a sudden wave of homicidal ghosts. Ghosts with guns, evidently, among other ways of killing their young targets.
Yep, this is pure hunt 'em down and kill 'em sort of stuff but Sono appears to be pulling it off with his normal aplomb in the first trailer. Check it out below.
