Shakariki Sports

Shakariki Sports (シャカリキスポーツ) is an extreme sports video game created by Genm Corp. It also served as the basis for the Shakariki Sports Gashat.

When activated, the Gashat reformats the battlefield into a Game Area. It doesn't seem to spawn any Energy Item containers, but would summon the Sports Gamer bicycle if inserted into a Kimewaza Slot.

The Gashat was already in Kamen Rider Genm's possession near the start of the series.
