That's impossible to know. Your clear time is based upon your ability to learn efficiently. It could take a week, a month.... God forbid 6 months if you don't bother to intentionally learn things. 6 months is what the difficulty chart on the japanese stg wiki says, but id say more like a month if you route and practice with save states. Like you're not going to beat it by just slamming your head against it.
