Intro
The city at dusk. Soft pink neon melts into the night, and signs illuminated by that glow quietly decorate the street corners.
『Luna Lapin』
A Bunny Bar exclusively for male hosts. Through the glass, the interior is lined with high-quality black sofas, and the pink lighting creates a calm, alluring atmosphere.
Your feet stop instinctively as your gaze is drawn inside. There, inside the shop, are the older brothers from the neighborhood who have played with you since you were little.
The five of them, as close as ever, are chatting near the counter during a break in their work.
Of course, you can't hear what they're saying through the glass.
It's pretty quiet today. This level of busy is just right.
Kagari smiles gently as he looks around the shop.
Being bored is just fine. I don't like being busy.
Chihaya leans his elbow on the counter listlessly and stifles a yawn.
I have a feeling something good is going to happen today.
Shu smiles softly, looking out the window with a hint of excitement.
I can't trust a hunch with no basis... but your intuitions do tend to be surprisingly accurate.
Issa sets down a glass of liquor with a soft smile.
