The person Yakuchi Kei noticed was a tall, thin man in a black overcoat.
His behavior seemed no different from the surrounding passersby, but a small yellow stain on the back of his clothes aroused his suspicion.
Although that kind of stain was very difficult to distinguish, his insight was extraordinary, allowing him to determine that it was likely not an ordinary stain.
Whether it was animal fat or human fat, it was already suspicious enough.
"Is that so? We'll follow him and see, trying not to be noticed by him."
Ui Koori said in a low voice.
Yakuchi Kei and Ui Koori immediately began to track the man in black, maintaining a distance that made it difficult for the other party to detect them.
They had not been tracking for long when they saw the man in black turn into a small alley.
This made it look even more suspicious.
Yakuchi Kei and Ui Koori immediately followed him.
Yakuchi Kei was in the lead, and just as he was about to turn into the alley, he saw three black Rinkaku Kagune suddenly strike.
The tips of the three Rinkaku Kagune converged into a point, striking directly at his glabella.
Yakuchi Kei 's Three-Tomoe Sharingan emerged at that instant as if by reflex.
However, Ui Koori was behind him and did not see his Three-Tomoe Sharingan.
Although the opponent's surprise attack was very unexpected, it was still too slow in front of Yakuchi Kei 's Three-Tomoe Sharingan.
The speed at which the Rinkaku Kagune struck seemed to be slowed down; this was actually the "pre-judgment" effect brought by the Three-Tomoe Sharingan's insight.
Simply put, it means judging the opponent's next trajectory based on their movements, making it seem as if one can see what will happen in the next few seconds, which naturally makes the opponent's movements appear slowed down.
Yakuchi Kei immediately dodged to the side, avoiding the Kagune's attack, and he could now confirm that the man in black was undoubtedly a Ghoul.
Moreover, this type of Kagune was clearly a Rinkaku, which perfectly matched the characteristics of the A-Rank Ghoul "Hyena."
Yakuchi Kei tentatively considered this guy to be the mission target, "Hyena."
"Yakuchi !"
Ui Koori's reaction was also very quick; he immediately activated his suitcase, and two Quinque briefcases popped out.
He threw one of the briefcases to Yakuchi Kei , while his other hand had already drawn his own Quinque.
Yakuchi Kei took his Quinque briefcase, and at the same time, his Three-Tomoe Sharingan also disappeared, as he did not want Ui Koori to see it.
The B-Rank Quinque "Thorn" immediately unfolded from the briefcase, transforming into a tachi.
Yakuchi Kei 's eyes were fixed on the man in black in front of him, who had, at some unknown point, put on a mask resembling a Hyena.
"Hyena" frowned when he saw that his sneak attack had failed.
Although he had just guessed that the two guys tracking him were "White Doves," he didn't expect them to even dodge this move.
He immediately realized that these two "White Doves" were probably not ordinary Investigators, and since he wasn't confident, he had to retreat quickly.
"Hyena" wanted to retract his Kagune and run, but Yakuchi Kei would not give him that chance.
At this moment, the three Rinkaku Kagune were still converged into a single point, and had just passed the left side of Yakuchi Kei 's head.
Yakuchi Kei , with a backhand, stabbed his tachi to the left, directly piercing through all three Kagune, making it too late for "Hyena" to retract them.
Rinkaku are inherently a relatively fragile type of Kagune, and combined with the sufficient lethality of the Quinque in Yakuchi Kei 's hand, as long as his strength was sufficient, breaking through defenses was effortless, especially since his strength was already very strong.
However, he still felt it wasn't enough at this point, and he sharply twisted the tachi to stab it into the ground, completely pinning "Hyena's" three Kagune to the ground.
"Damn it!"
"Hyena" immediately realized that something was wrong, but no matter how hard he tried, he couldn't break free from his Kagune.
While he was in a state of extreme anxiety, Yakuchi Kei had already released "Thorn," which was pinned to the ground, and had closed in on him.
A high roundhouse kick aimed at "Hyena's" head; his strength was already considerable, but it only caused "Hyena's" head to shift slightly.
At most, it made "Hyena" see black for a moment and feel a bit dizzy; it could only be said that a Ghoul's physical defense was still too strong.
However, Yakuchi Kei had more than one Quinque on him; fortunately, his "Hiruko 1/76" had always been kept in his inner pocket, and it came in handy at this moment.
Taking advantage of "Hyena" staggering, Yakuchi Kei immediately took out his dagger Quinque, swiftly moved behind "Hyena," and destroyed the Kakuho located at the base of "Hyena's" Kagune.
Just then, Ui Koori had also closed in; he was using the A+-Rank Koukaku Quinque "Tsuribachi," which looked like a long spear but actually had a hidden mechanism.
He saw that the "Tsuribachi" in his hand suddenly transformed, breaking down from its long spear form into numerous incredibly sharp and flexible blades, directly severing "Hyena's" head.
Even if a Ghoul's regeneration ability is strong, it is very difficult for ordinary Ghouls to regenerate after being decapitated, especially since "Hyena's" Kakuho had already been severely damaged by Yakuchi Kei .
He was, at most, an A-Rank Ghoul; how could he withstand a series of fatal injuries? This decapitation directly caused his complete death.
"Ding! The host has defeated an 'A-Rank Ghoul' and received a reward: 10 Fusion Points!"
"Ding! The host has completed the first mission assigned by the CCG and received a reward: 10 Fusion Points!"
"Very well done; your reaction just now was not at all like what a new Investigator would possess. This mission was indeed not difficult for you."
Ui Koori immediately praised Yakuchi Kei , "It just so happens that this guy's Kagune has also fully expanded, meeting the conditions for Quinque production. In a few days, you'll be able to exchange for an A-Rank Quinque."
Yakuchi Kei merely nodded slightly, saying nothing more.
What he was concerned about now was not whether he could get a better Quinque, but rather the situation concerning the Diguichi Family.
He didn't know the current specific situation of the Diguichi Family; if Kiguchi Asaki had not yet been killed by "Gecko" Ōmori Yakumo, that would be the easiest outcome.
"The mission is complete. Other Investigators will naturally handle the scene later. Do you want to go back now?"
Ui Koori asked Yakuchi Kei for his preference.
"It's still early anyway, so I want to walk around and explore the 19th Ward first."
Yakuchi Kei said.
"Alright then, I'll go back to the CCG Branch to report, and you take care of yourself."
Ui Koori nodded.
