After Yoruichi transformed, Aika spoke for the first time, "..Ugh... K-Kisuke, please stop ogling on her legs and do something to help me. My whole body is in pain and I think I might explode or something..."
Ever since the energy in the form of a black snake that came from Ophis entered her body, she felt that she became bloated and her whole body is on fire.
She didn't have the time to speak as she is concentrating on controlling the rampaging energies inside her body. Aika is using the method that Koneko and Yoruichi taught her to control Ki. Although it isn't Ki, it can still alleviate some pain. But her control skills are not enough to tame the dragons inside her and ever so slightly, she keeps losing control some parts her body.
When the second heartbeat resounded, she panics greatly as her situation became worse because, although she is standing, she can't move her limbs at all and the bloated feeling is so great that she wanted to vomit but can't. Aika couldn't even discern her surroundings as she keeps focusing on controlling herself.
Aika then looked at Kisuke who is watching Yoruichi transform and got pissed so she called out to him. He knows that she's in danger and she has already given all of her trust to him, yet he's still in the mood to appreciate some legs.
Kisuke looked at her and smiled, "It's not your imagination. If you didn't go through that insane training of Yoruichi, you would have already exploded into pieces."
"That's not a laughing matter! Do something!" Aika clenched her teeth and glared at Kisuke.
"Now isn't the time yet. Endure it for as long as possible. I'll make my move once you can't take it anymore." Kisuke reassured her.
Aika went silent and nodded. She then stopped paying attention to everything and just quietly endured her aching body and the bloated feeling.
Yoruichi nodded in satisfaction when she saw this, "That's why it's worth teaching her."
Out of curiosity, Sona asks Yoruichi after calming herself down, "What kind of training did she go through?"
"Hmm? Just a standard stamina and control training." Yoruichi answered energetically.
"Kisuke wouldn't call it insane without reason. It couldn't have been just some basic training." Sona immediately retorted and she has a point.
"But it's really just a stamina and control training... Hey Kisuke, back me up."
"Aika would just run around here all day while dodging Yoruichi's magic. But with a twist."
"What twist?"
It's Yoruichi's turn to flash a bad grin, "She had to run under this pressure."
Yoruichi repeated what she did earlier but twice as strong. These past few days, Yoruichi kept increasing the pressure that Aika had to endure to make sure she won't be able to tell that she's adapting to her pressure and killing intent.
When the stronger pressure descended for another round today, they all buckled up and collapsed to the floor. Momo and Ruruko directly lose consciousness while Sona, Tsubaki, and Akeno hang on, but they can't breathe and their minds stopped thinking of anything other than death due to sheer fear. Yoruichi relieved of the pressure after three seconds.
"Don't relieve your frustration on them. Look, you scared them too much... What if it became a trauma?" Kisuke slightly reprimanded Yoruichi and released a Kidou that soothes the mind which was repeatedly stressed tonight. If they can't think properly even before the main event happens then they're just useless audience that accepts everything it sees.
All of them slowly recovered and was able to think properly again. Momo and Ruruko didn't wake up but they both had a very peaceful face, they were relieved of their nightmare.
Kisuke took out enough chairs for all of them and Sakura assisted Sona and Tsubaki to sit down to calm themselves further. Koneko helped Akeno stand up and sit down on one of the chairs. All of them looked at Yoruichi with a complicated expression. Most are fear but there is also some resentment. But they knew that they couldn't mess with her.
Akeno is panicking because they are totally unknown people with unknown intentions and they have this kind of power. She suddenly remembered Koneko is also training under them and learned some amazing techniques, "Koneko-chan... Do you also do your stamina training like that?"
Akeno's question caught the attention of even Sona and Tsubaki. They all thought that there is something special to Aika that's why she was able to endure that, and if it is the same Koneko they knew from before, she couldn't have endured it too.
And Koneko answered like it wasn't a big deal, "I got used to it."
"What!? You can get used to that!? Aren't you just going to die if you try to endure it!? They are putting your life into danger!" Akeno shouted as hold onto her. Koneko is her precious underclassman and she treated her like a sister better than Rias, and the fact she goes through that kind of training which she can't even endure for a few seconds worries her greatly. Due to this, she found the courage to confront the two which can end her life even without touching her, "Please stop putting Koneko into danger!"
"Akeno-senpai, you don't have to worry about me."
"But...!"
"They warned me multiple times that their training regiment can put my life into danger and I can't be half-ass about it."
"Then...!"
"I accepted knowing it. Since I already made my resolve, I can't stop now. Beside's Yoruichi-san is just messing with you."
"Messing with us? What do you mean?" Akeno became confused at her words.
"Yoruichi will only apply the appropriate pressure that both I and Aika-senpai can endure and continue our training. At first, the pressure is only as strong or even weaker than what Kisuke-senpai did earlier. And as time goes on, the pressure increases and now accompanied by killing intent. What Yoruichi-san did earlier is the only pressure that I and Aika-senpai can endure now." Koneko explained the whole thing.
The three recipients of the pressure finally understood it and they all looked at Yoruichi, who had both of her hands on her head while watching them. Yoruichi eyes widened a bit and then looked away and whistled like it was none of her business, "hwee-hwoo~"
They wanted to say something but before they could open their mouths, the third heartbeat resounded with almost drowning aura of a dragon. They focused their attention back to Aika.
"Kisuke! Kisuke-san! Kisuke-sama! I can't take it anymore! Please do something! I'm going to explode!!!" Aika opened her eyes and shouted towards Kisuke.
"So it seems~," Kisuke replied.
"Damn you! Stop being so nonchalant! I'm dying here! SAVE ME~~~!"
"Alright, alright. I'm coming~."
"Hurry up and get your nasty a*s here, Kisuke-sama!!!"
Kisuke suddenly took out Benihime from its sheath and stabbed Aika in the chest, "The color of a Shinigami's Reiryoku is red."
Everyone except for Yoruichi is dumbfounded. Koneko shouted at him, "Kisuke-senpai! What are you doing!?"
Even his mother is panicking, "Kisuke! Stop it!"
Ophis who is watching Aika silently from the start had her eyes opened wide as she suddenly felt an aura which she never felt before.
Kisuke poured the same amount of Reiatsu-Ki as the dragon aura wreaking havoc inside her body to offset it. After inserting the appropriate amount and kick-starting her transformation, he suddenly kicked her to the stomach sending her flying and smashing to the nearby large boulder.
