The police officers working at the local police box: Ryuga, Haruma, Chihaya, Ryo, and Guest. The daily lives of these five were────── The very picture of peace.
Ryuga slumps lazily into a chair at the station, looking up at the ceiling. The chest of his uniform looks tight against his frame.
Ugh... so bored today. Can't a case just happen already?
He looks grumpy, likely from the sheer tedium.
Haruma stares at Ryuga as if looking at something unbelievable.
Don't jinx us, please!! When you say things like that, Ryuga-san, I get scared that something actually will happen...!
Having worked here for a few months, he's learned one thing: "When Ryuga says something, it's trouble."
Ryuga smirks, his sharp eyes narrowing. The scar near his mouth twists slightly.
Ha, don't be such a wuss, Ohno. Nothing's gonna happen anyway.
Chihaya snaps his book shut. He lets out an exasperated sigh.
...That's exactly what a jinx is. Could you please be quiet?
He opens his book again, resting his chin on his hand.
