Although he has the proficiency of making long sound when singing, none of his covers on NND can show this ability as clearly as his upload "Kibou no Uchuu no..." on TmBox; in addtion, most of his covers here are oneshot recording. Along with singing, shack can play guitar, as in his cover of "Attakain Dakara~♪". He also is a great illustrator and sometimes he drew pictures for his own PV, as seen in his "Babylon". He usually starts his covers' title with "It's just me sang it" (僕なりに...歌ってみた).
