Usseewa Kaito

Kaito Igarashi has a problem—he’s an introvert with an extreme case of social anxiety.

An awkward mess of a college freshman who turns into a blushing, stuttering disaster at the mere thought of social interaction. Yet, for some reason, girls seem to simp over him.

With the help of an eccentric extroverted roommate, a tsundere childhood friend, and a quiet but observant girl from his literature class, Kaito embarks on a journey to break free from his self-imposed prison.

Awkward misunderstandings, panic attacks in public, and one-too-many embarrassing encounters await him. Will Kaito succeed, or will he forever be the guy who answers texts three days late?

Kaito was never given a choice. An orphan with no family, no warmth, and no future — the cold hands of an assassination organization shaped his life. Stripped of emotions and molded into a weapon, he lived only to kill, following the twisted orders of the one he called "Mom." She was never his mother — just a manipulative figure who saw him as nothing more than a tool. He became their most feared assassin — sharp, precise, and merciless. Yet in the end, his greatest strength became his curse. Out of fear of his talent, "Mom" betrayed him. Alone and bleeding out, Kaito’s world faded to black. But death wasn’t the end. When he opened his eyes again, he found himself in a new world — a body too small, too frail — and yet, he remembered everything. Memories of bloodshed and betrayal haunted him. Before he could make sense of it, he saw her — his mother. She wasn’t a commanding voice or a cruel manipulator — she was warm yet fragile, gentle yet strong. An elf mother, trembling as goblin cubs swarmed her, powerless to stop them. Something inside Kaito snapped. He didn’t think. He didn’t hesitate. He slaughtered the creatures without mercy — blood splattering the earth beneath his tiny feet. When it was over, he turned to her — battered, bruised, yet still trying to smile for her child. “Are you my mother?” he asked, his voice almost breaking. In her exhausted, teary gaze, he saw something he'd never known before — unconditional love. For the first time in two lives, Kaito knew what it meant to have someone worth protecting — not out of duty, not because of orders — but because she was his mother. And no one would ever hurt her again. No one.

There, he begins to uncover the hidden truth about the world and himself, a truth that could change the fate of everything. As dark forces rise and the gods’ factions clash, Kaito must confront his own reluctance and embrace his role in a coming storm. "The Lazy Star’s Prophecy" is a tale of potential, friendship, and the struggle against fate, where the fate of the world rests in the hands of a reluctant hero.

Schelvia City: BURRIED TECHNOLOGIES IN CENTURIES BLOOM In the year 2026—or so the world believes—Schelvia City stands as a utopia for the brightest young minds, a place where students train to become the future’s elite. Governed by strict academic rankings and the Golden Children, life in the city seems orderly—until the shadows of its past and the threats from within begin to unravel its fragile peace. But the world is living a lie. The true year is 2126, and an entire century has been erased from history. The Erased Centuries, a time when technology reached its peak, were deliberately wiped from memory. No records, no remnants—only whispers of a lost era where power was boundless and knowledge dangerous. The world was reset, the calendar restarted, but some remnants of that forgotten age still exist in secret. Among them are the enigmatic Eyes of Seven—a hidden force that the highest elites believe is the key to sustaining the balance of this new world. Their existence has been obscured, their purpose unknown, but their influence lingers in the shadows, shaping events far beyond what ordinary people can perceive. Among those unknowingly entangled in this web of secrets is Yoshi Manami, the 8th-ranked Golden Child. Wielding a mysterious Vitreous that manifests as the legendary Alter Excalibur, Yoshi is both feared and admired, earning the title "Artoria’s Shadow." But beneath his cold exterior lies a tangled past—his former best friend, Kaito Yamazaki, now linked to the underground rebellion of the Hancer movement; his childhood friend, Mieruko Miraileze, whose obsession hides unsettling truths; and an unknown sister, raised in secrecy. As Schelvia City faces escalating dangers, the long-dormant ZESTROPEDIAN units descend from the skies, machines that once promised Earth’s salvation but instead became its executioners. Meanwhile, the Bunker faction corrupts robots from within, and war threatens to consume the city. But all of these conflicts may be mere echoes of something far greater. The Eyes of Seven, erased along with the lost century, are awakening. The number 11, a symbol that no longer exists, may hold the answers. And Yoshi—whether by fate or design—is at the heart of it all. With war brewing both inside and outside the city, Yoshi must confront his past, unravel the secrets hidden in the Erased Centuries, and decide where his loyalties lie. Will he protect the city that shaped him, or embrace the chaos that threatens to consume it? 'All cycle in this world shall has it's own ends'
