To learn 打首獄門同好会 - 布団の中から出たくない chords, your first step should be understanding these chords - C, G, C, G, Am and G in sequence. I suggest starting at a calm pace of 43 BPM, and as you gain confidence, approach the song's BPM of 87. Configure the capo to your vocal range and chord preference, remembering the key of C Major.
