Chapter 3: Final preparations
The next day, Momo woke up ate her breakfast and grabbed her Zanpakuto. She ran off to the secret location to train.
On the way to there, she passed by the Shinigami Research and Development Institute and waited for Nemu to pass her the peach hairclip.
When Nemu passed to her the hairclip, she said to Momo that she puts it on for the first time, it would use her current reiastu as the benchmark so in the future it would conceal the excess reiastu to the same level when it was first put on.
After putting it on, she thanked Nemu and left for the secret training ground.
When she reached the place stated at the map she saw an old house, she decided to go in and saw a trapdoor open leading downwards.
When she climbed down the ladder she saw a huge training ground.
She was looking at the place in disbelief as it is below a small old house.
All of a sudden Yoruichi appeared out of nowhere and gave Momo a shock.
Yoruichi then asked her whether the training ground is good enough for her.
She replied that it was more than enough.
Yoruichi then asked what kind of training is Momo doing here.
She replied in a confident voice, "Bankai Training."
Then Yoruichi asked her how long have she tried to subdue her zanpakuto spirit.
Momo replied softly, "I have not tried to subdue because previously I felt no need but now I feel that it is necessary to protect others."
Yoruichi asks her whether Momo is interested in achieving bankai within 3 days.
Momo was shocked that bankai can be achieve in a very short period of time.
Momo asked Yoruichi what was the catch for doing it.
Yoruichi explained, "You can only train for 3 days straight no more all else it would be dangerous to your life plus if you fail in this method you would have to train even harder for the next 10 years to achieve bankai."
Momo said in a determined tone, "Yes, I would do it."
Yoruichi then shunpo off and came back with Tenshintai.
Momo gave a surprised look and asked what it was.
Yoruichi said that the thing is called a Tenshintai and look like a white doll but it was an old item use by the stealth force to force a zanpakuto spirit to materialise into their world instead of you going into your inner mind to find them.
Momo continue to look amaze at the Tenshintai.
Yoruichi said, "To make your zanpakuto spirt materialise you need to stab the Tenshintai with your zanpakuto"
Momo excitedly asked, "Can I try it now?"
Yoruichi said with a smile, "Sure, why not?"
Momo grabbed her zanpakuto and stabbed it through the tenshintai.
Suddenly, a light appeared out of from the tenshintai.
When the light disappeared, a small girl appeared with brown hair dressed in a white kimono jacket, a purple hakama, a light yellow obi tied into a bow around her waist, two long ribbons on the end with a cylindrical shape hairclip on both bangs and a hairpin. She also carries two large bells attached to a pink sash which encircles her body.
Momo gasped in shock and said, "Tobiume is that you?"
Tobiume replied in a gentle voice, "Yes, it is me mistress."
Momo said in a slightly frustrated tone, "I told you to call me Momo for the past few times in my inner mind!"
Tobiume gave a smile and said, "Alright Momo, I heard your conversation just now and I would give you challenges and if you pass all of it then I would teach you bankai but if you cannot accomplish by the end of the 3rd day, then I would wait for you to subdue me."
Momo said, "Okay, so what is the first challenge?"
Tobiume smiled and said, "Hide and Seek"
