I know, I was suprised myself that it didn't hurt - certainly not like what I thought it would feel like! For me it felt as if someone took a ball point pen (and with some pressure) was writing on my back.
The Kanji symbol stands for "Fly" - I love Ravens/Crows (all birds in general but those are my favorites) and butterflies / dragonflies as well. And it does just so happen to be a SP song which is pure coincidence
Glad you guys like it!!
