Chainsaw Dash (チェーンソーのダッシュ) is the name of the first attainable upgrade for Juliet's Chainsaw. Adding exhaust pipes, a fuel gauge and a powerful engine, it allows Juliet to quickly dash forward, acting as a battering ram to any undead in its path. It is necessary to clear ramps frequently found throughout the stages.
The Chainsaw Dash is obtained from Morikawa on Stage 1 in the form of a birthday present for Juliet.
