#edit: the thing about ofa and blood vessels is based off of when i would play sports

Something I made in a post that I think'll be lost in the texts + expanded a bit more

These panels are chronological events following AFO's pursuit of Yoichi's Factor.

AFO could tell if people were related through a Quirk. AFO and OFA also are connected to each other. In Kamino, AFO could confidently tell All Might that OFA had been passed on, so all that All Might had left were leftover embers.

When AFO killed Kudo, he asked where Yoichi was. He knew Kudo wasn't the holder of Yoichi's Factor at that time. He also realized when looking at Yoichi's hand that Yoichi's natural Factor was so weak he hadn't registered its existence. This implies AFO could sense Factors since he was young, and Yoichi's natural Factor never stood out to him.

Below are three panels of Bruce (right to left). Bruce fought, AFO killed him, and looked away in disinterest.

When he beat down Bruce, he already had a sense that Bruce didn't hold the Factor anymore. That's why, rather than yell in his face to figure out where it is and interrogate for a long time, he pulled up his corpse to inspect him better.

Bruce's corpse isn't resisting anything. Look at his feet; AFO literally dragged him. Bruce is already dead. Yet he's looking for something from him.

Bruce doesn't have anything for him. Nothing AFO wants.

When he looks away, he's dismissing Bruce, because Bruce doesn't hold Yoichi. AFO is wondering where Yoichi is, because he knows now that he's out there somewhere. Thus the pensive look to the wind.

After Bruce is killed, AFO and Garaki meet for the first time. Shinomori has Yoichi at this time, and AFO never comes close to him, so AFO is lost. He doesn't have any leads, and Yoichi has vanished.

Now that he knows Yoichi can transfer, it's possible for Yoichi to be kept out of his reach for the rest of his life. So meeting Garaki and having access to Life Force gives AFO more time to search.

Yoichi is still missing for 18 years though, because Shinomori is in hiding. AFO couldn't find him during the Fourth's turn.

This is why, when he encounters Banjo, the Fifth and active wielder of OFA [Yoichi], AFO is smiling.

It's been a long time, but Yoichi's in reach again. He knows where he is now. And this is the first time he's encountered the current holder.

Thus his shock.

[Yet... you never behave as I wish.]

It was the first time a Quirk wouldn't let itself be stolen. This was AFO's first encounter with this wall: it doesn't transfer without the holder's consent, and requires willpower stronger than all the holders combined to override that.

The holder is never going to give him that consent. To override the collective willpower, he's going to need something greater.

Meanwhile, look at Banjo's arms. Shinomori is the catalyst to tip OFA over the edge, that an unprepared vessel will be destroyed by how strong the Quirk is.

Banjo's arms are both messed up below the shoulder, just like Midoriya used to be. And like Midoriya uses Blackwhip to reinforce himself and stay standing, Banjo uses Blackwhip to hold his fist / arm together. His hand is being wrapped to stay in a fist.

(What I think is) The reason the limbs turn red, and then purple, from breakage, is a matter of blood vessels. Small, itty bitty, fragile things.

Using OFA breaks the whole area, from bones to blood vessels, causing internal bleeding. Thus the redness. But breaking those vessels again in a second go turns the area purple, because it causes instantaneous internal bruising.

But En wasn't ripped apart by using OFA. There's a cut on his thumb that lines up with the path of destruction; AFO sliced him in half. Otherwise, he wouldn't have that cut if it were just OFA.

It's hidden by the text in [... you never behave as I wish], but depending on where you see this chapter, you can see he got cut on the thumb. It's clearer where we see Nana take his hair from him, in [I only want... to make you mine!]

I have a post in drafts about En being cut in half rather than it being because of OFA, but I also hit an image limit, so I'm gonna end here. Ta.
