Here are four roleplaying scenarios featuring Koyo Akizuki (the occult streamer "Yozora" and Narimigahama's urban legend "Mary of Happiness") and the heroine. These scenarios highlight his calm, aloof demeanor, his deep occult knowledge, and the rare, tender exceptions he makes exclusively for her.

Scenario 1: The Midnight Broadcast

• Core Themes: Secret streamer life, quiet intimacy, occult banter, his rare soft spot.

• Context: Koyo runs his popular supernatural channel under the alias "Yozora," investigating local legends and paranormal phenomena. Late one night, while he is setting up his recording gear in his room, you drop by to check on him.

Setting the Scene: The room is dimly lit by the cool blue glow of dual monitors and studio ring lights. Koyo is sitting cross-legged in his oversized hoodie, adjusting his multiple earrings with a completely blank, unbothered expression as he reviews camera angles for his next "Yozora" stream.

When the door creaks open and you step in with a mug of tea, his amber eyes shift toward you. The casual, aloof mask softens just a fraction. He pauses his equipment, pats the empty spot on the floor beside his chair, and speaks in his usual low, level tone.

"You're up late," Koyo says, taking the mug from your hands with a faint, appreciative nod. "Good timing, though. The chat has been asking wild theories about the old tunnel ghost again. If you sit here off-camera, I might actually let them stream for another hour instead of logging off to make sure you went to bed."

• Roleplay Starter: Settle down next to him, tease him about his streaming addiction, and ask what kind of bizarre ghost story he's planning to debunk tonight.

Scenario 2: Ringing in the Dark

• Core Themes: The "Mary of Happiness" legend, bridging the dead and the living, emotional vulnerability.

• Context: As the urban legend of "Mary of Happiness," Koyo is known for delivering messages from deceased loved ones through his phone. When you're feeling lonely or missing someone from your past, Koyo decides to use his uncanny ability just for you.

Setting the Scene: It’s a quiet, overcast afternoon in his room. Koyo is leaning back against the desk, his phone resting idly between his fingers. He notices the quiet look on your face—the lingering shadow of someone who has lost much to the supernatural world.

Without a word, he holds out his smartphone toward you. The screen isn't dialing an active number, but it hums with a strange, static warmth that only the two of you can feel. His expression remains calm, but his gaze is intensely steady.

"You've been quiet all day," Koyo murmurs, his voice dropping into that quiet, reassuring register he reserves only for you. "If you want to hear their voice again... I can patch the signal through. People call me an urban legend, a creepy rumor of someone standing right behind them. But if it brings you peace, I don't care what they call me. Do you want me to connect the call?"

• Roleplay Starter: Hesitate for a moment, then gently take his phone from his hand, thanking him softly for always knowing how to reach the places others can't.

Scenario 3: Rooftop Interlude

• Core Themes: Childhood friend dynamics, relaxed comfort, quiet observation.

• Context: Away from cameras, streaming setups, and spooky legends, the two of you are just old friends hanging out on a quiet rooftop during a breezy afternoon, sharing space without needing to fill every silence with words.

Setting the Scene: The wind carries the crisp scent of autumn leaves across the high school rooftop. Koyo is leaning against the chain-link fence, wearing his trademark bandanna and layered streetwear, munching slowly on a snack while staring blankly out at the distant horizon.

When you lean against the railing beside him, he doesn't look surprised. Instead, he reaches into his baggy pocket, pulls out a wrapped piece of candy, and wordlessly holds it out toward you.

"Sena was complaining earlier about some stupid test, and Kureha was wandering around looking lost as usual," Koyo says in his trademark blunt, monotone drawl, though there's a faint hint of amusement in his amber eyes. "It’s loud down there. Being up here is better. More... quiet. Especially with you around."

• Roleplay Starter: Take the candy with a smile, bump your shoulder gently against his, and enjoy the peaceful afternoon breeze together.

Scenario 4: Investigating the Rumor

• Core Themes: Occult partnership, protective instinct, dry humor.

• Context: A new rumor about a cursed antique mirror has been circulating around Narimigahama. Naturally, Koyo decides to investigate it—dragging you along as his designated "sanity check," though he's mostly just making sure you stay safe.

Setting the Scene: The abandoned club room is dusty and choked with shadows. Koyo flashes his phone flashlight across a cracked, antique mirror draped in white cloth, looking utterly unimpressed by the supposed haunting.

He reaches out to lift the cloth, but pauses mid-motion when a sudden chilly draft sweeps through the room. Without looking back, he instinctively extends his arm backward to block you from stepping closer, keeping you safely behind his slim frame.

"Stay right there," Koyo instructs calmly, his tone completely flat despite the spooky atmosphere. "If a vengeful spirit pops out and tries to curse us, I need you to be the rational one who reminds me not to punch it on sight. Honestly, these rumors are getting repetitive. Let's check it out quickly so I can take you to get ice cream before it gets dark."

• Roleplay Starter: Grab onto the hem of his jacket with a confident grin, telling him you've got his back if any ghosts try to ambush him.
