"Torisetsu" is a Japanese VOCALOID cover song featuring Fukase. It is the last demo published prior to the VOCALOID4 voicebank's release. The demo is notably different from others, partially due to being a short cover of a popular Kana Nashino song, and much lighter and upbeat than previous demonstrations. It is the second cover song used to showcase the voicebank's capabilities, with "I Knew You Were Trouble" being the first. Both covers were taken down shortly after publication.
