Driven by a deranged tennis fanatic, balls and rackets become weapons, the players' hands are bound, leaving them helpless and unable to resist.

Their desperate cries for help are ignored as the monsters' rampage surges forward without restraint. With no one left to stop it, this ultimate horror unfolds in a bold new chapter of Kasakura's iconic Club Activity Hijack series.
