Flow. Present name Fate.

Flow is a protagonist of a story that has been scrapped. Only she was saved.

The story was called Flow Barrier. It was one of the latest installments for the BetaMeta saga.
But since it has no place in the lore, it didn't make the cut, and Flow is the surviving proof that the story ever existed.

In Flow Barrier, Flow lived a normal life with her friends. Until she started seeing... disturbances.
These disturbances were the Flow Barriers. They disrupt the normal everyday life in the form of bad luck. They are unseen to the naked eye, and it was up to Flow to defeat these unseen monsters.

Flow being the sole Transistor in this world, she has the ability to somehow conjure energy out of thin air. When in reality she merely channels energy from other planes of existence through her own body as a medium.

Trivia, this story was inspired by The World Ends with You with the Noise bringing negativity into people's minds.
