Despite being labelled as 1 cut, the handwriting completely changes between Mirio and Tamaki

The shot of mirio is esentially confirmed Nireki via handwriting imo

Mayyyybe the other person here is Hino? It's hard to say since they have very little actually credited here, but some of the timing and smears seem somewhat similar to their work on (post #148911)

Not tagging since again there's little to go off of. Just giving some ideas.
