"I feel like a broken record but you really have changed huh." Cracking a wide smile, Doctor Isshin/Soichirou proceeds to walk forward, leading you as he makes it to his special bookcase. Lifting one of the placed books to have it roll up into the ceiling, revealing a secret pathway. "Follow me."
Nodding in response, both you and Satsuki proceed to follow him into the secret pathway. Finding yourself walking down countless stairs as the two of you went down a spiraling, almost double helix-like structure. It would've been easy to just grab the doctor and jump down to the bottom. Descending with the grace of a heavenly angel or dragon, but both of you decided to refrain from showing off. There was no need to rush things after all. You did however place another hand on Satsuki's father's body. Assisting in his disguise and mending any repercussions made by his forceful transformation trick. Much to his shock and fundamentally his gratitude.
Eventually, both you, Satsuki, and Isshin reach the secret underground facility where you continue to follow him. It wouldn't take you any longer as you see where your sibling Senketsu was located. True to the doctor's words they were still undergoing the chrysalis process as they were surrounded in a cocoon-like sphere. The heavy lifting has already been established as well as the copious donations of Ryuuko's DNA carefully spread out throughout the years. Leaving you to put the finishing touches as you made your way to Senketsu.
Finding yourself fully transformed as Junketsu Shinzui, you further consolidate your true-life fiber synchronization and undergo singularity. With a gentle motion of the hand, you begin to sprout what appears to be snow-white feathery wings from your back. Appearing more angelic and divine to the doctor, you merely move both hands against the cocoon. Without even touching it, you start to emit a powerful, yet gentle deluge of power and energy into the sphere. Sharing your very essence and the accumulated culmination of life fibers you've stacked up during your stay with Satsuki to Senketsu.
Unsurprisingly, this miraculous display of power would transmogrify the dormant godrobe. Accelerating their development by leaps and bounds as you share what you and Satsuki build up with Senketsu. From this harmonic resonance, you feel Senketsu's essence beginning to flow in you mutually. Just as you were giving something to Senketsu, they were instinctively rewarding you with something of theirs as well. You felt yourself becoming stronger, much stronger. Was this the power of sibling bonds? Or was it merely another case of the power of love taking root differently? Truthfully, you couldn't say.
Amuse by this, you merely continue the process as Senketsu's development soon reaches its natural conclusion before awakening is imminent. But he wouldn't awaken as was planned, no. For she now has a human body.
