Here is the first solo movie Yoko/Kaede did for DEEP's. I would guess she is about 19 or 20 in this video and clearly pretty new to the business. This isn't her AV debut, though, just the first one for this company. However, this is one of the more intense debut titles I've seen, but that seems fitting for Yoko.
