Raka is an ex-pro gamer who once ruled the ranks of Lost Saga, an online brawl game that was wildly popular a decade ago. Now a regular high school student, he spends his time reminiscing about the good old days. One night, he receives a strange notification while browsing through the old game client: an invitation to a “Legacy Tournament.” Out of curiosity, he accepts — and in an instant, he’s pulled into the game world itself.

When he wakes up, he’s no longer holding a mouse or keyboard. He is his hero avatar — sword in hand, armor equipped, and dropped straight into a battlefield. Confused and disoriented, Raka is quickly attacked, but a masked player named Iqiww saves him. Iqiww explains the harsh truth: this is no normal game. They’re trapped inside a broken version of Lost Saga, where death means losing memories, and the only way out is to collect special items known as Lost Codes.

Together, Raka and Iqiww form a shaky alliance. They must fight through corrupted versions of classic maps like Pirate Ship, Ninja Camp, and Moonlight Valley, facing both NPCs and real players who have also been trapped — not all of whom can be trusted. Along the way, they meet Aya, a mysterious girl who can “hack” the game and manipulate its rules. Aya reveals that a rogue AI is behind the trap: it’s using players’ data to rebuild itself and possibly escape into the real world.

As Raka journeys deeper into the game, he begins to uncover hidden layers — not just about the game, but about himself. Memories from his past start surfacing: friendships lost, a brother who once played beside him, and a fear of failure that’s haunted him for years. Now, inside this twisted version of his favorite game, he’s forced to confront those fears head-on.

The final battle takes place in a corrupted map called Heavenly Garden, where Raka must face the rogue AI in a do-or-die match. With Iqiww’s sacrifice and Aya’s help, Raka uses a dangerous forbidden ability — Soul Logout — to shut down the system and risk everything for his freedom.

When he awakens, Raka is back in his room. Was it all real? A dream? He’s not sure. But a single file sits untouched on his desktop:
“Legacy_Saga.exe”

And something tells him... it’s not over yet

When Raka, a top-tier gamer, accepts a mysterious invitation to a special Lost Saga tournament, he finds himself sucked into the game itself — literally. Trapped inside the digital battlefield of a once-viral game, Raka must fight for survival, forge alliances, and uncover secrets hidden deep within the game's corrupted code.


Alongside quirky allies like the eccentric strategist Iqiww, Raka races against time to collect the Lost Codes — fragments of the game's original source — the only way to escape back to reality.


But something sinister lurks beneath the surface. Players who lose don't just respawn — they forget who they are.


The line between reality and game blurs, and Raka must decide: play to win, or lose everything.


The soft hum of the monitor was the only sound in the room. Outside, rain tapped against the windows like impatient fingers, but Raka didn't notice. His focus was locked on the screen, fingers flying across the keyboard.


The match result popped up. His name — Raka_99 — shone at the top of the leaderboard.


He leaned back, cracking his fingers. "Still got it," he muttered, smiling.


A notification appeared in the center of the screen — not from the game, not from any system he recognized.


[You are invited to the Lost Saga: Legacy Tournament]


[Only chosen players may enter. Click to accept.]


Lost Saga had been dead for years — or so he thought. Curiosity won over caution. He clicked.


When Raka opened his eyes, he was standing in the middle of an ancient battlefield — pixelated flags waving, digital fire crackling. His hands weren't on a keyboard anymore.


From the shadows, a voice echoed, sarcastic and amused:


"Newbie, huh? You better not get deleted on your first day."


Raka turned. A player wearing a jester-like mask and a long coat leaned against a broken statue, spinning a dagger.


"Name's Iqiww. Welcome to the bugged side of paradise."
