Overview
サヨナラチェーンソー (Sayonara Chainsaw, "Goodbye Chainsaw") is a VOCALOID original song by Kurage-P (Takeaki Wada) featuring the voice of Yuzuki Yukari. It was first released on the 2012 doujin album 少女戦争 (Shōjo Sensō / "Girl War") under the circle ARMS, with a music video created by チェリ子 (Cheriko). The track made its rhythm-game debut in SEGA's CHUNITHM AMAZON PLUS in April 2019 before arriving in maimai DX later that December.
The song's high-energy composition matches its lyrical theme: a narrator drowning in the ceaseless noise of gossip and daily irritation fantasizes about revving a chainsaw engine to cut through the mental clutter. The refrain's exuberant "サヨナラバイバイ！！" (goodbye, bye-bye!) delivers a cathartic release, driven by a propulsive 154 BPM beat. In maimai, both the Expert and Master charts were designed by はっぴー (Happy). The Master chart sits at level 12 with a constant of 12.5, characterized by dense Tap patterns and generous Slide and Touch segments that mirror the song's relentless churn-and-release energy.
