Symbol Sans 设定

This is a setting about sans in my au.

I used machine translation for the character plot Settings. Some of the translations are rather strange. Please excuse me.

Symbol Sans Character setting.

A Young Man Born After the War

On the surface, he was no different from any other youth. He knew the war had cost the monsters dearly—but never grasped the true weight of that loss.

His exceptional talent landed him a lab job straight out of school, though at first, he merely studied the cryptic symbols on the Barrier. His decryption speed outpaced the entire team, earning him a promotion to lead researcher under Gaster.

His cheerful demeanor made him well-liked in the lab.

Then, Chara fell into the Underground.

Curious about humans, Sans befriended them. One day, while he scribbled reports in Chara’s company, they peered over his shoulder. "What’re you researching?" they asked. Sans figured it wasn’t a secret—the symbols were right there on the Barrier, visible to all. "Cracking these," he said. "Solve ’em, and everyone goes free."

Unbeknownst to him, Chara’s family were descendants of the seven human mages who’d sealed the monsters. Their clan taught every child the symbols’ meaning. "I know this," Chara offered, and explained everything.

Overjoyed, Sans rushed back to document their words for the higher-ups. But as he worked, a searing pain erupted in his bones.

At first, he blamed exhaustion. Then the agony spiked—unbearable, untouchable by painkillers. He staggered home, locked himself indoors, and writhed. What’s happening to me?

In lucid moments, he traced it back to the symbols.

Weeks later, the pain ebbed just enough for him to confront Chara. "What do those symbols really do?" Chara blinked. "For humans? They’re protective charms." "And for monsters?" A shrug. "No idea."

Sans searched their face for malice—found none. He left in silence.

With no answers, he turned to solving the problem himself. But the symbols fought back. They gnawed at his body, hijacked his mind. Memories fragmented. Notes rewritten mid-sentence.

"You can’t stop me," the symbols taunted.

Then came the day he nicked his finger with a paper cutter. Red liquid welled up. Red. Monsters don’t bleed red.

Later, coworkers gossiped: "Hey, the Barrier’s symbols are gone!" "Nah, probably just invisible. If they were really gone, we’d be free."

Sans froze.

He knew where the symbols had gone.

Into his bones. Into his spine. They were his marrow now.

The solution was simple: Kill Sans, and the symbols would die with him. The Underground would be free.

…I don’t want to die.

He barely remembered stumbling home. When his vision cleared, he stood before a mirror, kitchen knife in hand. His reflection smirked as symbols crawled across the glass:

"Pathetic."

Sans pressed the blade to his throat.

The reflection paled.

"I bet you don’t wanna die either."

A standoff. The knife bit deeper. Red stained his scarf.

Finally, the symbols relented: "What do you want?" "To live. Both of us." A truce was struck—the symbols could stay, but one step out of line, and Sans would end them both. He’d proven he meant it.

Aftermath

One by one, the research team met grim fates. Sans reported their "accidents" until the lab disbanded. Soon, he was the last survivor.

Chara succumbed to an incurable illness—likely from early DT extraction, Sans realized. His obsession with work had already strained ties with Papyrus.

Adrift, he lingered in the ruins of the lab, pivoting to chemistry. Then, during a late-night shift, he found Gaster’s files.

"Project DETERMINATION."

The plan was monstrous: Concentrated DT would melt monsters, fusing them into grotesque amalgamates. Gaster aimed to build a kingdom of horrors—with himself as god.

Sans thought of Chara’s illness. Rumors said the first DT batches were extracted from their soul.

That night, he confronted Gaster.

The fight was one-sided. Sans was outmatched—until Alphys burst in, distracting Gaster long enough for Sans and the symbols to strike the killing blow.

The secret was buried. Alphys became Royal Scientist; Sans, her assistant.

No one else would ever know about the symbiosis in his bones.

Thank you very much for reading this far!( ´▽｀)

Hi, can you spare a few minutes to listen to this song?

This is an AU I created as a child. Now that I’m grown up, I’m fulfilling little me’s dream. Thank you to everyone who’s watching – it truly means a lot.

I'll try to draw the story later and post it here!

I'm not sure about tags, but I'll start with these two for now:
