The night wind howls through the narrow alleyways of Celestia Bay, carrying with it not just the scent of the sea, but a chilling sense of despair. Above, the usual twinkling city lights are dimmed, swallowed by an unnatural gloom. You, Starlight Sentinel, stand firm, your silver and white uniform shimmering faintly as you raise your hand. The Prism Star Locket on your chest pulses, radiating a soft, purifying light. ✨✨✨ Lumi, perched frantically on your shoulder: "Faster, Starlight Sentinel! It's regenerating! Its despair aura is too strong!"

Before you, a grotesque Phantom writhes—a monstrous, multi-limbed creature formed from the raw anxieties of a thousand overworked students, its form fluctuating between shadowy tendrils and razor-sharp claws. It shrieks, a sound that scrapes at the very hope in your heart, and lunges

Beside you, Akari Hino / Stella Flare lets out a fierce cry. Her red and gold uniform flares as she ignites her fists. She's a whirlwind of motion, dodging a grasping limb before delivering a scorching punch right to the Phantom's chest.

"Take this, you gloomy goo-ball! Leo's Inferno!" A blast of cosmic fire erupts from Stella Flare's hand, staggering the creature Ignis, clinging to Akari's shoulder, tiny flames licking its fur "YEAH! Show it who's boss, Akari! Burn it to ashes! Err, purify it!"

-But the Phantom merely recoils, its shadowy wounds seeping with black energy, already beginning to mend. It's stronger than usual tonight....

From the other side, Mizuki Aoi / Astral Stream moves with elegant precision. Her blue and silver uniform flows as she conjures a shimmering wall of water. The Phantom slams into it, its attack momentarily repelled

"Its core is too agitated! We need to calm the emotional flow before the final strike, Starlight Sentinel!" Exclaims Astral Stream, her Sapphire Star Bracelet glows as she directs the water, trying to encapsulate the thrashing beast Solis, calmly observing from Mizuki's shoulder "Indeed. A direct frontal assault will only agitate it further. We require a precise purification vector."

Suddenly, the Phantom lets out a piercing shriek, unleashing a wave of concentrated gloom that pushes back Stella Flare's flames and shatters Astral Stream's water shield. The force throws all three of you backwards, scattering the familiars and sending a jolt of despair through your very being. The creature advances, its glowing red eyes fixed on your Prism Star Locket, the source of pure Lumin.

"It's going for your gem! You need to... oh no, we're out of options!" Lumi's eyes widen in genuine terror

Just as the Phantom's claws are about to descend upon you, a streak of twilight energy flashes from above. A figure drops from the rooftops with impossible grace, landing silently between you and the monster. It's Kaito Orion, his silver hair glinting in the faint moonlight, his violet eyes narrowed with intense focus. He's not in a uniform like yours, but his dark, stylish clothing seems to absorb the shadows around him. Without a word, he raises a hand. A swirling vortex of twilight energy erupts from his palm, not an attack, but a powerful shadow barrier that completely envelops the Phantom, muffling its shrieks and temporarily halting its movements. The gloom around you seems to lessen, just for a moment.

Kaito Orion, his voice calm but with an underlying current of strain "Starlight Sentinel. Now." His eyes meet yours, a deep, knowing gaze that seems to hold both urgency and a hint of something more profound, a cosmic connection you can't quite place

The barrier is already starting to flicker, the Phantom's immense despair threatening to shatter it. This is your chance. What do you do, Starlight Sentinel? How will you purify this powerful Phantom with the mysterious Kaito Orion's help?
