A fluctuation shadow has been waiting for occured when Kei broke the glass. "Hurry up and get stronger". Shadow barely managed to send Kei these words. Shadow was almost caught, but "that entity" shouldn't have noticed it.
At those words Kei's pupils shrunk. His whole body got coated in black I energy, and he started observing his surroundings cautiously. After a few minutes of looking around, and trying to communicate back. He just let out a sight and went to his bed. After setting his alarm clock to 9 am he directly slept.
Being able to hear these words made shadow believe he hadn't chosen wrongly. Shaodw couldn't send an easier to receive mental message. At K's current level of strength it's practically impossible to receive it. But he did.
Certainly it was nice that he had good health, was smart, a genius in fact, cause he wouldn't have collected all of this info without being one, and his personality wasn't outright horrible. That isn't enough though cause he isn't best in the world in any of those regards.
But he had something that makes it easier for shadow to help him. A black hole in his chest. The reason an empty vessel was only hypothetical was cause an empty vessel isn't exactly having no emotions at all.
Not having emotions at all made a mythical type of vessel called the absolute zero vessel, but the empty vessel was on the premise of having a negative value if quantifying emotions was possible. It's not possible to have a natural empty vessel as a body is like a room.
Even if you don't put anything there and it appears empty. It's not really empty. To make it fully empty you need to suck the air out and make it into a vacuum. His black hole sucked emotions. He wasn't born emotionless, but he seems to have been forced to keep accumulating his rage and not act upon it.
Eventually it solidified and kept compressing. After doing this a lot he stopped putting in effort, as he managed to make a black hole when he started compressing all of his other negative emotions as well.
The black holes base was rage, and so all of his emotions turned to rage upon getting sucked, and that's what shadow needed a person with a sea like rage. His alone isn't enough to be the person with the most rage in the world, but his body being vacuumised of emotions caused him to suck in other people's negative emotions as well.
Unauthorized duplication: this tale has been taken without consent. Report sightings.
He doesn't feel that rage anymore and doesn't act upon it. Anyway his black hole kept getting larger the more he absorbed other people's emotions. On the other hand, people found themselves somehow getting comfortable when they get in touch with him.
Shadow hasn't been observing humans one by one. He was looking at a high concentration of wrath. Instead of emmiting it he was actually sucking it in so he was hard to notice. It took a great deal of investigation. Eventually shadow noticed a low level of negative emotions in a certain area which made him wonder if someone was accumulating them.
After observing for a while and noticing how he can't read the mind of kei, shadow paid close attention which led to his night switch and eventually shadow noticed how negative emotions flow toward him and get sucked inside but K never shows it on his face as if he doesn't feel them.
After connecting with him and sending him this message shadow finally became able to read his mind. Not completely though. He can't tell if the black hole was formed consciously or by instinct. For all he knows it can't have possibly be formed by instinct as to form it that way he'd have needed much more rage than what K originally had.
On the other hand, he couldn't have done it consciously as It would have needed an amount of control unfathomable even for shadow. Not to mention if K really can control it he just has to stop rotating the black hole the way it is right now and start rotating it in the opposite direction.
The abyss in there will flood out and it should bring catastrophes with it. The will inside that abyss had reached the point where it doesn't want to obtain justice for the suffering he had went through, but rather it wanted to exterminate the whole world.
The sun rose up. A "kuroko no basket" opening started going from the alarm set on his phone. Kei practically exploded out of bed. In a matter of 5 minutes he got done with everything he had to do and was already out of his house. Compared to the power saving mode he's been in during the last month, it feels like he was hit by lightning to suddenly get all of this energy.
After going to Andy's house at the appointed time they went to the living and played some games while waiting for their other 2 friends. Andy was a 1.81m tall guy. He was pretty tall but being so thin that he was underweight made him look like he was a stick.
Kei had an average height of 1.72m, but when standing next to andy specially with how Kei has a good build and Andy has a skinny one Kei seems like he's a dwarf. "So when do u think Yato and Jimmy will come?"-Andy
"Yato always comes 15 to 20 min late so he should be here any minute now, as for Jimmy....you have been his friend even before me so you should know that not to mention coming on time even just coming is something highly doubtful." - Kei
They hear the ring of the door bell afterward and Andy goes to check out who's there. Meanwhile Kei grabs the controller and starts playing with both sides to increase his score goals in fifa." That's what you get. I'm the best in almost all types of games except for football related ones since I hate them, and yet he always makes us play fifa cause he knows it's the only game he has a chance of winning against me in."
Andy walks back with Yato and Jimmy in tow, which prompts Kei to turn off the console." Well, now that we are finally all here and no one else is in this extra house let's stop wasting time and go directly into business. "Said Kei while cracking his fingers in expectation.
