This song has a version sung by Utsu-P and a version sung by Gumi but I took both versions to make a duet. The video is Utsu-P wearing a giraffe mask and playing guitar but filmed in very very low quality.
If you want to use the version sung by Utsu-P only : https://www.nicovideo.jp/watch/sm17236307 If you want to use the version sung by Gumi only : https://youtu.be/c7b00ihJ1dk (you need to adjust the latency if you use this one) If you bought the Super Shiborikasu album and want to use the version from that album, you can. You can simply put the audio file from the album instead of the video, or if you are able to, you can make your own video or replace the sound from the target url video.
