After "Period", "Again" is my second favorite OP from what is arguably the best anime series ever. It's a musically rather simple piece that draws most of its allure from its interesting rhythmic patterns. Especially the pre-chorus part that just hacks on the E is pretty awesome. You can see a very useful technique to repeatedly play the same note rapidly here.
I compared different arrangement that existed and went with Marvin Liu's one. Some adjustments were made, but the sheets are still largely identical to what I'm playing.
