That's curious. My conceptions of what Yoshiki might be like somewht correspond to Taiji's point of view.
Intelligent. Spoiled and selfish, absolutely. Very concerned about himself, "high maintenace" of his public image. An actor. Unbelievably detemined and hardworking. Somewhat masochist too. And, at the same time, a very human and caring person. Extremely busy with himself yet always ready to comfort and listen. Sometimes father, sometimes son.
But innocent. I think this is his most outstanding feature. Innocence. The innocence achieved by one who's experienced life a lot yet never lost the inner childish-ness, the purity and the will to love. Love. A constant in his life.
Almost all rockstars loose their identity when they reach super-stardom. Yoshiki is the real example of someone who never did.
An intense person, maybe diffiult to deal with sometimes. But someone worth meeting at least once.
That's how I see Yoshiki, myself. I don't him very well, actually. I'm not even a die-hard fan. But what a coincidence. I think this is basically what Taiji tried to say.
