Sui-Feng came to learn the possession technique from Yoruichi, but she instead became the next practicing target as the naughty Yoruichi attempted to possess both her and Orihime at the same time. First, to show off her mastry of the possession technique, Yoruichi transformed Orihime's body into a hybride combination of the two of them. Nexit, she grabbed hold of Sui-Feng's breasts and began infusing her own Reiatsu into it, causing them to enlarge until they are now the same sizes as the possessed Orihime. Sui-Feng was stunned by with this. She hated how Yoruichi modified her body without any warning, but she can't denine the fact that she was enjoying it.
While Sui-Feng was distracted in her own conflicting thoughts, Yoruichi snapped her fingers, casting the possession technique using the Reiatsu she had just infused into Sui-Feng. Sui-Feng, in a moment of weakness, was completely caught off-guard. In just a few seconds, her mind and consciousness were fully synched with Yoruichi's. With Sui-Feng now under her complete control, Yoruichi began to slowly transfer even more of her own Reiatsu from Orihime into Sui-Feng's body. Bit by bit, the possessed Sui-Feng began to transform even further.
