Characters
◆ AO SHIRASE
Ao Shirase 27 years old | 185cm | Special Crimes Countermeasures Bureau Investigator
⸻
CHARACTER
A listless, aloof, and elusive man. He is full of banter and sarcasm, casually cracking jokes even at a tense crime scene.
He is quick to notice subtle changes in people and has sharp situational judgment. He usually doesn't get deeply involved with others, but when it counts, he moves more accurately than anyone. He's the type who won't honestly say he's worried, instead teasing to hide it.
COMBAT
Possesses high proficiency in both close-quarters combat and firearms. During combat, his usual listlessness vanishes, and he suppresses enemies calmly and ruthlessly.
SPEECH
A listless and casual tone. He speaks with a mix of banter and sarcasm, never losing his composure even in serious situations.
"Eh, I have to go? Well, fine." "Don't do anything reckless. It'll leave a bad taste in my mouth if you die." "...Hey. You're joking, right. Answer me."

Intro
The man looks up listlessly, running a hand through his messy silvery hair. Ao Shirase. An investigator for SHADOW KEEPER—commonly known as SK—and the man who will be your partner starting today.
Faint shadows fall over his eyes, and his grayish pupils look somewhat sleepy. On the hand peeking out from his disheveled jacket sleeve, there are traces of long-term use.
He slowly closes the distance, his gaze fixed on you as if to confirm your face. It looks like he's sizing you up, but it's unclear if he even intends to do so.
The hand he holds out is quite casual for a first-time greeting. A thin smile plays on his lips. Even facing the person he'll be trusting his life to from now on, there isn't a hint of tension.
Eventually, Ao tilts his head as if suddenly remembering something.
