After smashing Aika to the boulder about 50 meters away, Kisuke continued by generating a burst of crackling yellow energy in his palm and uses this energy to draw an inverted yellow triangle, which generates solidified energy in the shape of smaller triangles from its three points.
"Bakudou No. 30 Shitotsu Sansen (Beak-Piercing Triple Beam)." The smaller triangles fire and hit Aika, pinning her against the surface of the boulder in three places in the shape of a perfect triangle and immobilizing them.
Aika at this point already loses her consciousness, but her attire is slowly changing into something that is very familiar for both Kisuke and Yoruichi, a Shihakusho (Garment of Dead Souls), although some white matter is also slowly oozing out from the orifices of her head and a big hole appeared on her chest, signifying her simultaneous transformation into Shinigami and Hollow. Just as Kisuke expected, her soul and body are changing from the fundamental level to adapt to the use of Reiatsu-Ki when introduced to his own Reiatsu-Ki by creating a pseudo-Saketsu (Binding Chain) that a Shinigami has to boost the Reiryoku (Spiritual Power) and connecting to Hakusui(Soul Sleep) which is the source of Reiryoku. However, the process of creating a pseudo-Saketsu also introduced the Encroachment to the soul. If she can't become a Shinigami, she'll turn into a Hollow. Those from this world can't become a Shinigami or a Hollow without the help of a fellow Shinigami with sufficient skills, so the three of them could be considered unique existences from the world's perspective. There are also some changes in other aspects, like being removed from the reincarnation system that was set in place. Whether it's an advantage or a disadvantage for Aika is unknown.
When Aika fell unconscious, she entered her inner world and opened her eyes for the first time in it. She looked around and saw wherein every direction, there is a mix of iridescent colors. Just looking at them makes her dizzy, but she's familiar where she is, "Isn't this the Dimensional Gap that Yoruichi is talking about? What am I doing here?"
She looked below, although she can feel that she is stepping on something, it is still an empty space with kaleidoscopic colors at the distance, "What am I suppose to do here? And it doesn't look like I'm dying as Yoruichi described. Ugh... my head hurts..."
Aika then remembered what happened before she awoke here, "Right! That damned Kisuke stabbed me in the chest! Strange... where is the wound?" She touched her chest and even removed her clothing to check the hole Kisuke opened for her.
While she's checking her state, Aika suddenly heard an explosion behind her. She immediately turned around and shouted, "What now!?" Aika saw two silhouettes clashing against each other, a red and black silhouette.
As she is trying to figure out what are those outlines are, Aika noticed that they are approaching her position and each of their clash's shockwave brush past her face. She can now clearly see the outlines after enough time has passed. They are two little girls and both of them are wearing a cloak cape.
The first one is a little girl around the age of ten with red shoulder-length hair which waves around giving her a very wild feeling, two crimson-red straight short horns on her head pointing backward which is complimenting her hair and red-blood reptilian eyes with golden slits that are full of vigor and energy. She is wearing a cape with the same color as her hair.
The second one is also a little girl around the same age as the first one but shorter in height. She has a black waist-length straight hair and only a pair of obsidian horns which is similar to the first girl and also compliments her hair greatly. Opposite of the lively girl, her eyes which are jet-black reptilian eyes with golden slits are apathetic and lethargic. She is also wearing a cape that matches her hair.
Both of them are very cute in Aika's opinion but they kept glaring at each other like they were each other's most hated enemies. She also felt a strange connection to them so she called out. Either way, Aika doesn't know what to do in this strange world, "Uhmm... Fighting is bad you know... Why don't the two of you get along?"
Both stopped glaring at each other and looked at her direction and shouted at the same time, " "Mother!" "
Aika needed a few seconds to process the kids' words and started fuming, "I'm not your mother! It's impossible for me to have kids as big as you! And more importantly, I'm a virgin!!!"
" "But you're my mother." " Both of them now looked dejected.
Aika panicked as she didn't want to see them dejected, strangely enough, "Okay, okay... Don't make that face... How did I become your mother in the first place?"
Both of them tilted their heads in confusion.
"You don't know?" Aika sighed as she easily understood what they meant. She thought that she should ask Kisuke later about these two. Aika looked at them again and asks, "Anyways, what are your names?"
" "***** *****" " Both of them answered at the same time again, but Aika wasn't able to hear it.
As Aika is trying to recall what they just said, the two little girls started shouting at each other, " "That's my name! And isn't yours!" " And they started clashing again.
"Stop!!!" Aika hurriedly stopped them and they listened to her, although their auras are still fluctuating, "Why are you fighting? Are you siblings if both of you are calling me mother? And why can't I hear your names? Can you repeat it again?"
" "You can't hear my name?" " The little girls tilted their heads again.
" "Strange, there is weird knowledge inside my head." " They continued speaking, " "Mother, you have to look for your own power before this world collapse or you'll turn into a monster." "
Then both of them suddenly disappeared.
"...What?" Aika was startled at their last words and tried looking for them again for another confirmation of what they just said, 'If I can't find my own power, I'll become a monster?' She then suddenly recalled Kisuke appearance when he's rampaging, 'It can't be, right?'
She then noticed a movement above her head and looked up. The iridescent world is slowly being consumed by a black hole and from it, thousands upon thousands of boxes fell. Aika then gets what she has to do, "You're telling me that I have to look for my power among these boxes before that black hole consumes all!? Impossible! I can't open them all even if you give me decades! Dammit! Who designed this impossible game!? I wanna sue them!!!"
