Sora got plenty of info he could use from all 3 of them and proceded to talk with his system about which has the Highest chance to wake them up normally...
Sora: "So System, which way is the most efficient and safe among them??"
System: "The safest one would be to give them Hollow powers. This will place a seed in their souls after healing them and each time they got closer to their death or feel negative emotions it will grow to form their own Dark Self."
Sora: "Hmmm, i really don't want to go to the Zero Squad... Actually, it's a miracle they haven't made an appearance yet..."
Sora: "Therefore i'll use this..."
D. Sora: "So, you decided to go with my plan??"
Sora: "Yeah, but can we avoid their hollowfication process at least till they awake??"
D. Sora: "It won't happen, as we have similar types of souls..."
Sora after going through one more time with his plan he turned and started telling Unohana about his plan, since she is his wife he should let her know right??
Unohana: "Are you crazy?? Then won't you become like Aizen??"
Sora: "Aizen's ways are simply trash, my way is top quality..."
Unohana was speechless yet she could see a confident look in his face as if he was saying a piece of cake...
Sora took a deep breath and called his hollow mask which caused the room to start crack from the Reiatsu he was emitting...
He then raised his hands and placed them in their chests where their hearts located before injecting them with Cero type strands of reiatsu.
As he did so his mask started getting thinner and thinner, at first it was like 2cm thick but now it went like 1,99 - 1,98 and went down to 1,50...
He gave 0.25 each of them, which was enough to heal them and place a bud inside them.
Sora then placed his hand in the mask before making it go completely away as if he had never worn it.
Sora: "Now we can only wait..."
Inside of their own soul realm, the girls started waking up and reach in two different words stunning them...
Karin's inner world was like rocky mountains, while Yuzu's was like a plain field full of flowers...
Both of them were puzzled as to how they had reached this place and started looking around for any clues as to where they were and how they got here...
They tried to remember their last few memories and an intense pain started assaulting their heads. Both of them fell in their knees as their memories started resurfacing and remembering about a few well-dressed guys beating them up...
As the feeling of pain came back to them they also remembered that in the last moments of fading away they heard they wanted to kill Sora...
They started breathing heavily and an incredibly raged came forth from them as they always ended up causing their family problems from being too weak...
Their eyes turned yellow and white drops started forming in their faces...
Sora who was outside and was seeing this situation was speechless and at the same time kept talking with Gyaku, a weakly Dark Sora and his System on how to solve their hollowfication...
Unohana: "I thought you said you had it under control!!!!"
Sora: "I did ok!!! Something must have happened to them when they got captured or heard something and when they waked up they remembered it..."
Unohana: "And how is that related to this..."
Sora: "The small part of hollow i gave them, needs to grow as time passes to control it... But since they sunk themselves to negative emotions like anger or hatred it started transforming them to genius hollows."
