It seems that there are a few albums where Tenpei Sato is credited together with a person named Strawberry Boy.
Red ~ The Adventurous Sequence
According to
http://www.alchemics.co.jp/users/bandit/album/red.htm Tenpei Sato and Strawberry Boy composed the BGM.
Beast Dramatic Music Collection
According to
http://www.alchemics.co.jp/users/bandit/album/beast.htm Tenpei Sato did the music with Strawberry Boy.
CAL ~ The Eternal Beautiful Girls
As we can see in the scans, also All Music Compose: Tenpei Sato with Strawberry Boy
http://gyusyabu.ddo.jp/MP3/1991/CAL2.html lists Strawberry Boy as sole composer for CAL II.
http://www.lt.sakura.ne.jp/~kawahagi...eview/cal.html goes as far as assuming Strawberry Boy is Tenpei Sato
I know
Mirage SUPER ARRANGE VERSION also credits Strawberry Boy for the music, though I have no proof right now.
Hiroaki Sano lists Mirage2 in his works (
http://www.swary.com/works), but I am now unsure if this game's music was included at all (no source either).
What I'm trying to say is there is a possibility that Strawberry Boy could be a pseudonym of Tenpei Sato.
