The spin-off plan of the DropEraser! RulerBattle becomes the application and appears! A battle this time insane with a ruler! More than 40 kinds as for the usable ruler and pen in total! We defeat an enemy, and let's obtain all rulers! A play is possible to up to four people with the Multi-play mode! It is sure that I get well by the lunch break and a drinking session!
