This is a great song, I've been playing it for awhile, and realized that it was
also the first ending of Death Note, which made the song more popular, so I
figured I might as well post it. I figured this out by ear, and I hope that it is
precise. You can compare it to the actual song if you wish. These are the chords,
I mostly based them off of the sound of the main guitar. AGain, I figured this
out by ear, it might not be very presice.
