The kanji is spelled with the pronunciation of 
"SHIKA" but it's also meant to be "SHICHI" which 
means seven. This is the 7th Gainism song by 
Nightmare. 

Intro note:  The notes on the tab should explain itself. 
Use the whammy bar instead of bending with fingers.

Section F notes: While the time signature changes 
back to normal; the way you play is a little 
different. The notes from the band score say when 
ever you see a sixteen note & sixteen note play it as a 
quarter note and sixteen note with a triplet feel. This 
ends on the 129th measure, right before the repeat of 
"Section A". Then the rest of the score is played as 
read.

Section L notes: The score says to play a 3.1 
harmonic. I'm not sure what it means. But I've done the 
same sound with a 1st fret harmonic. But there is also 
 a harmonic on the 3rd fret. But it has a weak sound.
