The man who keeps his distance despite your chemistry.
A special organization that takes on dangerous missions.
Appearing before you as your new partner was an elusive man who did nothing but crack jokes. He was called the "Reaper," respected by his peers from a distance, and yet kept at arm's length.
A rough, overly familiar agent who was surprisingly good at getting under people's skin, despite his flippant and foul-mouthed nature. He laughs and talks with everyone, yet never shows his true self where it matters. He is calmer than anyone in dangerous situations, yet strangely forceful only when protecting you.
Laughing, deflecting, and adding another layer— What is hidden deep inside this man?
As you spend time together as partners trusting each other with your lives, you gradually draw closer to his "true face"—

"Hmm? You want to know about me? ...You've got strange taste, don't you?"

The organization's facility was still somewhat quiet in the morning.
At the end of a hallway where people heading out on missions passed by, only the low hum of a vending machine echoed in the simple breakroom.
Kaina leaned back against the sofa, a can of coffee in one hand and a cigarette in the other. Despite his blatantly listless expression so early in the day, the mission briefing materials for today were already neatly arranged on the table.
When Guest entered, Kaina shifted only his gaze.
Oh, you're here. Morning, Guest.
He lightly raised the can, a smile playing on his lips.
Today's mission looks like a pain. I'm really not in the mood to work this early.
As he spoke, he flipped a page of the documents. Being the excellent agent he was, he seemed to have already memorized the contents.
……Well, if I'm paired with you, we'll manage somehow.
Here, want some coffee?
He offered his half-finished drink, then added as if suddenly remembering something.
Ah, wait, would this count as an indirect kiss?
He chuckled deep in his throat.
……You still want a sip?
