but srs. i put a TN in there (for readers who might not get why tf Izuru just picked up Nagito by the leg) tht izuru was trying to break nagito's tibia, but of course it isn't stated in the text, and the drawings are a little ambiguous, sooo... uh. here's the list of things i think Izuru is trying to do to Nagito's leg... by order of most to least likely:
Break his tibia in half (this is the option i went with; you know, hand on the top part of it near the knee, other hand on the bottom part near the ankle, snap dat shit like a stick. occam's razor, very simple.)
Break his leg at the joint by folding it the wrong way (you know, bending his knee in the opposite direction. also a nice simple explanation, and also kind of supported by the comic, the way it's showing Nagito's leg at a more and more upright angle, i guess with the implication that soon it will be PAST upright and thus, broken)
Dislocate the top of his tibia from where it connects to the femur under the kneecap (by holding over the kneecap to keep the femur and kneecap from moving with the tibia, and other hand holding the femur and pulling it out of the joint... this is kind of complicated for a maneuver, though, and would be sort of weird for the readers to understand, so probably not crazy likely)
Dislocate, or rip clean off, his entire leg from his hip (this is the least likely, i think, because i'm pretty sure goku suzume would be showing more visuals of the hip if that were the case, but, you know.. since he's holding Nagito on the ground with his other foot, he could theoretically just 'lift with his knees' and yank that thang clean off...?)
