This is another PARANOiA, with speed changes from 75-300, and a video which scares people. Apparently.
The artist is NAOKI, this time with the pseudonym a-type300 (the 'a' is a Greek alpha symbol).
While the Heavy steps are only a difficulty of 9, there are many difficult parts which players believe make it a 10. The Challenge steps are very difficult, with a final long 8th note death run containing crossovers and jumps.
B-3, L-7, S-8, H-9, C-10
