*Turbo Assisted Rapid Intelligence, also known as T.A.R.I. or colloquially known as Tari, is the main protagonist of Meta Runner. She is one of many professional Meta Runners, but unlike other Meta Runners, she has an ability that allows her to transfer her mind into any video game she plays.

It was initially believed that Tari was the test subject for Project Blue that Dr. Sheridan used to test his program with her as the human host, but archived security footage shows that the real subject was Lucinia Porter, who had gone missing two years prior to the show until it was revealed by Derek Lucks near the end of Fatal Error that Tari herself is the A.I. that Sheridan created to enhance a Meta Runner's gaming performance.

However, an accident occured during the project which resulted in Lucinia having her mind shattered with a part of it attaching to the T.A.R.I. program but caused Tari's memories to be erased and she was implanted into an artificial body by the psychologically damaged Sheridan and left in a safehouse in the back alleys of Silica City, with no idea of who or what she was.

Tari wears a blue and white hooded jacket over a white tank top with her Meta Runner symbol, brown khaki pants, white and blue socks, and brown flip flop sandals. She has short blue hair with a fringe covering her right eye (Half of it is exposed in Season 2), blue eyebrows (as of Season 2), and purple eyes.

Her Meta Runner Arm is on her left.

Her appearance resembles the Blue Jay Bird. In particular, her symbol and the designs on her jacket's shoulders resemble its wings.

During her time as a TAS Corp. representative, her outfit switches to a bare-shouldered, black, white and blue TAS Corp. uniform and black tracksuit pants with white stripes, and navy blue slide sandals with long socks with blue stripes.

Starting from Soft Lock, she once again wears her iconic blue hoodie over her TAS Corp. uniform but with a few differences, including the thicker black lines.

Tari is depicted as being a very kind-hearted girl who enjoys hanging out with people in order to get to know them, displaying a friendly mood around the people she hangs out with and cares for them and their safety.

Despite her innocence nature, she is shown as being insecure and shy, playing the role as a pacifist when it comes to solving conflicts through words rather than actions which sometimes ends up failing. Her persona is a result of a combination of confusion when trying to understand a problem and a lack of confidence within her ability to solve a situation that makes her very prone to danger.

But in terms of her inabilities in her confidence, she has shown be have grown during her time in TAS Corp., displaying a more mature and "cooler" mood as stated by Theo due to learning from Belle, as well as more reckless and passive-aggressive as she taunts Evelyn to distract her during their fight in the corrupted version of Ultra Jump Mania.

After escaping TAS-Corp and learning about her true identity, she is depicted as a more bolder character, lacking most of her self-sensitive trait, showing confidence whenever a situation presets itself and putting herself at risk to protect others.

But this is most likely because after learning her identity, Tari started thinking lowly of herself as seen in "The End", when talking to the AI version of Lucks, she was willing to rip herself apart to return Lucinia to the friends and life she had before Tari "came along", showing she holds herself in a very low light due to being the one having the fragments of Lucinia's mind that were given to her after Lucinia was blown up.*
