I found on my space that YOSHIKI had olso other nicknames like Miyuki Igarashi, Tomomi Tachibana, Ryu Shiratori, MacDonald Douglas.
But... maybe it`s just rumor.
I`m sorry for my English, I`m still learning.
Tomomi Tachibana and Douglas MacDonald???
Well, the second one sounds somehow familiar to me, but never in connection to Yoshiki - but I don't know where I know it from.
And I think those names are none of Yoshiki's pseudonyms.
But Hitomi Shiratori is right - X's drummer, songwriter (of X, Easy Fight Rambling, Orgasm, Stab Me in the Back, and co-writer of Tears) and a punk-character as far as I know
Then Igarashi Miyuki hime (Songwriter of Standing Sex)... a positive pole of Yoshiki's alter ego
and it is
Rei Shiratori - the brother of Hitomi and drummer of L.O.X
And I think the reason why Yoshiki AND Hitomi wrote 'Tears' is because everything in Yoshiki wrote it - he did it with all his heart and not because of a simple mood like... well you can see that Hitomi wrote the rather agressive and more rocking songs, which had a more positive mood and were rather about to have fun than songs written under the name 'Yoshiki'.
