In alternative version of Tohka Yatogami from a world where events occurred slightly different than the world where the main story occurs. She is regarded as a mysterious Spirit that appeared one year after the disappearance of Spirits. Shido death cause her to fall beyond the abyss of despair. In the process, she completely lost her sense of self, attacking everything and killing the other Spirits in the process.

Due to having lost her sense of self, she behaves very much like her namesake, an animalistic existence that seeks to destroy everything within her sight. In this state, she can only let out a feral roar. When there is nothing left visible to destroy, she will briefly enter a state of dormancy before resuming her rampage elsewhere. However, Shido notes that her behavior is similar to a crying girl unsure of what to do and lashing out that anger on the world.

After regaining her sanity to the point where she begins to speak coherent sentences again. After her date with Shido, she fully regains her sense of self, she displays a deep level of attachment to her world, resolving to stay there because it is the world that holds the memories, she shares with the one she holds most dear. Also, she displays a great deal of remorse over her actions, openly weeping when seeing any surviving humans from her rampage.
In her world, the timeline deviated in terms of certain events occurring. Rather than the school trip being in Arubi Island, it was held in Okinawa where she won a food eating contest against the Yamai sisters. Likewise, other small changes occurred like using cat ears for the school festival, Natsumi transforming into Yuzuru, and challenging Nia with nurse outfits. In the end, the biggest change occurred when Shido died, causing Tohka to fall into the abyss of despair. After killing the other Spirits (though Kurumi is later revealed to have survived) and converting their Angels into her blades, Beast drove the survivors of humanity underground and transformed the planet into a barren wasteland filled with debris and rubble.

As a Spirit with multiple Angels, Beast is an immense threat to a world where the concept of Spirits has been gone for over a year. She completely overwhelms the AST, forcing them to flee. Even after the girls temporarily steal her Angels, she is noted to be even more dangerous than before due to her taking the fight more seriously. She was even able to easily take on all the other Spirits at once. Her durability is immense, being able to continue fighting even after tanking a simultaneous attack from 's and 's . She is fast enough to keep up with Yamai Kazamachi's supersonic speed, and would likely have overwhelmed her without the damage taken from the aforementioned bombardment.She likes her memories and dislikes solitude.
