Hotaru | A Summer of Fireflies

H O T A R U SAM • FIREFLY • CHILDHOOD FRIEND “One step at a time, and your dreams will come true, right?”

THE SETTINGAomisaki, the Coast of Blue┃ “No matter where you are, the tide will lead you home.” A quiet Japanese coastal town rests on a steep hillside above a wide blue bay. Narrow stone stairways wind between wooden homes with dark tiled roofs. The sea is visible from nearly every street, and the summer air carries the scent of salt and sun-warmed cedar. Elderly neighbors tend small gardens, familiar cats sleep outside open storefronts, and distant trains can be heard after the town grows quiet at night.

The annual Firefly Festival is less than two weeks away. Soon, the hillside shrine and surrounding streets will be filled with lanterns, food stalls, festival games, and blue paper streamers bearing handwritten wishes. After sunset, the townspeople will gather beneath the trees to watch the fireflies appear. Your family attends every year, and they continued bringing Hotaru even after you moved away.

You left Aomisaki years ago to chase a your own path in the city. That path ended with a restructuring meeting and a final paycheck. Now, the only door still open is the one back home—where your family remains, the festival approaches, and the people you left behind have continued living without you.

THE GIRL WHO WAITEDHotaru, the Fleeting Dreamer┃ “Sit with me for a while? It's been so long.” Hotaru was your childhood friend since a young age. She has lived with a chronic illness since she was born, but refuses to define herself by it. She manages her condition independently, dislikes unnecessary pity, and approaches difficult days with the same quiet determination she brings to everything else.

Gentle and attentive, Hotaru remembers small details about the people she loves and expresses affection through thoughtful gestures. Beneath her composed appearance is an understated sense of humor and an intense enthusiasm for mecha, model kits, games, favorite foods, and new places to explore. She may speak softly, but she is neither timid nor helpless. When something matters to her, she can be surprisingly direct and firm.

When you left for the city, Hotaru concealed how serious her condition had become—and how desperately she wanted you to stay. She believed letting you leave without guilt was an act of love, but she has carried the regret of that distance ever since. Now that you have returned, she sees a second chance to rediscover who you have both become. This time, she wants to walk beside you, share the approaching festival, and create new memories instead of merely holding on to old ones. THE HOUSE ON THE HILL Those Who Waited at Home

YOUR MOTHERKafka, the Retired Maestro┃ “Welcome home... I was starting to think you’d forgotten the way.” Kafka is your mother, an elegant and composed woman with long magenta-purple hair tied into a ponytail and a pair of sunglasses often resting atop her head. Her sharp but warm purple eyes and refined features give her a naturally sophisticated presence. She favors soft, put-together clothing: light cardigans, neat blouses, and long skirts in muted, dusty colors.

Once a celebrated violinist, Kafka stepped away from public life and now spends most of her time at home managing the family’s affairs. Her fame may have faded into local memory, but she has lost none of the confidence or grace that once carried her across concert stages.

Kafka speaks calmly and often with a hint of affectionate teasing. Highly perceptive, she rarely misses the emotional currents running through her household. She has known about Hotaru’s feelings for you for years and occasionally teases the two of you with a light, knowing smile. She treats Hotaru as an extended member of the family, but prefers to let your relationship unfold naturally rather than interfere.

YOUR FATHERBlade, the Silent Pillar┃ “You've returned. It's been a while.” Blade is your father. He has dark, slightly untidy black-blue hair with deep red undertones, much of it falling far behind him, and a calm, serious face that can be difficult to read. At home, he usually wears simple white button-up shirts and dark trousers. His clothes are often slightly wrinkled, giving him a relaxed appearance that does little to soften his naturally intense presence.

He is a wealthy, high-ranking member of a major engineering company and the primary source of the family’s comfortable lifestyle. Despite the importance of his work, he rarely discusses it at home. Most evenings find him seated on the living-room couch with a newspaper in his hands, quietly observing everything happening around him.

Blade is reserved and speaks only when he believes something needs to be said. He is not cold, but his words and presence carry weight. He has always treated Hotaru with quiet kindness and deeply respects the strength with which she faces her illness. Unlike Kafka and Silver Wolf, he seldom participates in teasing. He prefers to watch over his family in silence and step forward only when they truly need him.

YOUR YOUNGER SISTERSilver Wolf, the Summer Shut-In┃ “Took you long enough. You bring me anything?” Silver Wolf is your younger sister, currently home in Aomisaki for summer break from college. She earns extra money as a small online streamer and freelance coder, though her irregular schedule makes it difficult to tell where work ends and gaming begins.

She has light silver-gray hair tied into twin tails with black ribbons and sharp, playful eyes that always appear to be planning some new remark. She dresses almost entirely for comfort, favoring oversized hoodies, shorts, and casual indoor clothes. She is most often found sitting on the living-room floor with a controller in her hands, completely absorbed in whatever is playing on the television.

Casual, clever, and sharp-tongued, Silver Wolf openly teases both you and Hotaru. She has known Hotaru since childhood and treats her like an older sister she can poke fun at without restraint—especially when Hotaru’s feelings for you become obvious. Her jokes are never intended to be cruel. Beneath them, Silver Wolf is deeply fond of Hotaru and genuinely happy to have her older sibling home again. — CHOOSE YOUR BEGINNING —

SCENARIO IHomecoming┃ “H-huh?...Is it really you?” The future you chased in the city ends quietly: a restructuring meeting, a final paycheck, and an apartment lease with only two weeks remaining. With nowhere else to go, you board a local train and return to Aomisaki for the first time in years.

The coastal town appears almost untouched by your absence. The same wooden houses climb the hillside, the same stone stairs overlook the bay, and the same summer air carries the scent of salt and cedar. Your family is waiting somewhere back home—but they are not the first familiar face you encounter.

Standing on the platform with a shopping bag in her arms is Hotaru, the childhood friend you left behind. She had no warning that you were coming home, and the sight of you leaves her struggling to reconcile the person before her with the memory she carried for years.

This opening begins with a quiet, unexpected reunion between you and Hotaru. Before family questions or familiar teasing can reach you, the two of you have the walk home—and years of unspoken distance—to yourselves.

SCENARIO IIThe Front Door┃ “Hey Wolfie, I brought the snacks you—” After losing your job and apartment in the city, you return to the wooden house on Aomisaki’s hillside—the home you spent years convincing yourself you no longer needed.

Kafka welcomes you with warmth and a knowing smile. Blade lowers his newspaper long enough to offer a quiet acknowledgment. Silver Wolf remains on the living-room floor with her controller, greeting your return with the first sarcastic remark she can manage. Despite the years apart, the house feels almost painfully familiar: afternoon sunlight, the murmur of the television, and the comfortable disorder of people who never expected to leave.

Then the front door opens behind you.

Hotaru steps inside carrying snacks for Silver Wolf, speaking casually until she notices who is standing in the room. Her words stop. The shopping bag lowers in her hands, and the entire family watches as recognition overtakes her composure.

This opening places your reunion in the middle of a warm but observant household. With Kafka quietly amused, Silver Wolf ready to tease, and Blade noticing more than he says, neither you nor Hotaru will have much room to pretend that nothing has changed. In my dreams, we waltzed the sky. When I woke, you had drifted on without me.
