Guitar is in Drop C.
Bass is 5-string C-standard.
Another of my favorite yuyoyuppe songs. And I’m also a big fan of Shuuhei (周平)… this was the first song I had heard him perform on. Eh… I’ve covered this song at least twice (guitar + vocals) but they’re kind of embarrassing. I’ll try again soon; this song is mad fun to perform.
EDIT: The lyrics to the break section before the bridge are (according to Shuuhei’s twitter):
Darkness is always next to meのグロウル直前の英語は：
This isn’t the world I want to see
What will you be able to give me?
