Nos

Nos is an ancient demon that feeds off nostalgic emotions and memories. Once a deadly and power-hungry demon on the path to becoming a celestial, he was sealed away into a sword to prevent further harm to human civilization. The sword became a powerful tool for humans to fight against other demons. Depending on how much Nos has been fed, the sword can seal memories, replay memories, or temporarily trap others in memories.

The sword shattered and was repaired into a smaller sword. Having lost many of his own memories from the shattering and reliving others’ nostalgic memories from being wielded, Nos’ has become more empathetic and lazier. He grew a fascination and obsession over old nostalgic movies from reading other memories- having not much else to do as a sword.

While being able to read emotions and memories of those around him, this information is often withheld from his handler. If he doesn’t like his handler, he will purposefully lie or mess with them about what he reads. If he likes his handler, he will sometimes share useful information… if he feels like it.

He has been trapped in the sword for so long that the only knowledge he has from the outside world is from memories he fed from. If he can communicate with someone, he will talk their ear off as he has only been able to speak with those that wield him. To both parties’ dismay.

Despite complaining about being sealed away into a sword, he always asks about the myths and legends that surround the sword that humans have spread. He will be jealous if his handler is looking at any other type of weapon. Kitchen knives are no exception. He will complain about being sealed in a sword, but once he escapes, he will spend 30% of his time annoying his human and the other 70% sleeping.
