Jujutsu Kaisen, Vol. 4

This volume has, by far, the best moment of Yuji as a protagonist.

If you've made it so far thinking that Yuji often falls behind in terms of characterization compared to other more notable characters (Sukuna, Gojo, and even Megumi) you wouldn't be wrong. BUT, in this volume, Yuji has what I consider a “monstrous” development as a character and as a protagonist. This is due to the circumstances that he's faced with, that of fighting against his new friend while at the same time attempting to maintain his previously established beliefs intact.

That gives way to, so far, the most brilliant moment of the series that also leads to the best fight of the series (again, until this point) because of all the narrative construction until that point as well as the riveting action.
