Chet

"——The Eighth Bullet, Chet"
Accompanying Kurumi's voice, the clock hands in her left eye moved clockwise at an alarming speed. The shadow that emerged from the
Roman numeral [VIII] was sucked into the muzzle of the handgun.
After that Kurumi slowly aimed the muzzle of the handgun now loaded with the shadow at her temple, and unhesitatingly pulled the trigger. Instantly, Kurumi's head violently shook due to the impact through it, her body splitting into two.
No, the words needed to correctly describe it were a little different. From
Kurumi, there emerged another Kurumi… putting it this way would be more
fitting.
Zafkiel's eighth Bullet, Chet, was a bullet that, when loaded and shot at herself could produce clones from "her past up till
now" which would split from her.
The clones' physical limits was scaled with the amount of time that Chet consumed.
In other words, in order to produce long lasting clones. Kurumi would have to expend large amounts of "time".
"Honestly. It's such a high maintenance spoiled child."
