Kamen Rider #4 (2015)

Original title: dビデオスペシャル 仮面ライダー4号

A time loop created by the Shocker resets whenever someone dies... but whenever the loop resets Shocker itself somehow grows stronger and stronger. It is up to Kamen Riders Drive, Faiz, Mach and Zeronos to decide whether to keep on fighting a useless battle... or end the loops for good by sacrificing one of their own.
