My favorite part in the animated Toji vs Gojo Round 2? The way Gojo says "Red". The VA had done so well here. It's just one word but you can feel his giddiness, glee, and awe at the fact that he can now cast it.
Ngl tho. Seeing Toji's reaction to the bloody doughnut on his side was depressing. It didn't hit hard when I read it but seeing it animated just nailed it for me.
However! The best fight scenes goes to Geto! I don't care if he lost. His scenes were so cool! Seeing him do a Yu Yu Hakusho Spirit Gun equivalent made me giddy.
Now, the most disgusting part of EP4: I can't decide between the scene of Amanai being presented on the table like a slab of meat or the cult of assholes applauding her death. I really really wished Geto didn't stop Gojo just ending all of them there.
The best shot in the episode: this incredibly loaded scene.
