This Assassin Is UprightThis Assassin Is Open and Aboveboard

The assassin you imagine: sneaking in silence, lurking in the shadows, emerging from the corner to strike with lethal precision, and vanishing without a trace. But Yu Zhun’s code is different: declaring loudly like a chuunibyou (delusional teenager), "My name is Yu Zhun, and I'm here to kill you today!" One-hit kill! One-hit kill!! One-hit kill!!! The most useless SSS-rank assassin talent, yet in Yu Zhun's hands, it becomes the strongest! (Accqq, translated)
