I'm not sure where to post this, but I found that both さの隆 and 佐野タカシ are listed as SANO Takashi, however the former is author of Tetsu no Ou - Deus Ex Machina and Kimi ga Bokura wo Akuma to Yonda Koro (and maybe others), while the latter is the author of most of the other works. 佐野タカシ also has a wikipedia page that can be used to help identify which works are his.
