Shes super athletic and fast. Official Volume notes show that she basically appeared in front of sakurada cuz she's super agile, u can see her chasing in one of the panel's and in the staircase it's implied she got down faster cuz she jumped down.
Next chapters will show her carry 120kg of cement mix like it's nothing too
Also she created a whole mental image of her skeletal structure, down to even the angle at which her wisdom teeth that are not out yet are about to grow, she fucking saw her future with echolocation!
By listening to the sound of blood rushing through your brain's capillaries and the pulse of your neurons firing she can infer what you are thinking...
