天上天下唯我独尊

Toga made Ochako go above and beyond, true, but that's because Ochako was willing to do that for her. They are such an essential part of each other in the good sense— it happened between fights, true, but the results came with not from the hits, but from the words exchanged.

It started as two girls who have a crush on the same boy and ended up with two teenage women who recognized each other as people beyond the hero and villain status. Ochako recognized Toga's agency, respected it and chose to trust her with it and in return, Toga paid in full and saved Ochako's life with her own blood.

Ochako is really one of the only characters that discarded the hero and villain ideals and dared to care for them as humans. Deku is not an almighty god, he needs help. Toga is not a terrible monster, she needs help. Etc.

Hell, Ochako verbally recognized the importance of the League of Villains to Toga, recognizing that they loved her and she loved them. She granted the same sense to them that she granted Toga, the knowledge that they weren't monsters. She didn't care solely to stop them or save them or defeat them— she hoped to save Toga, to make Toga stop because she didn't want to continue, to dissolve the reason to fight altogether.

Ochako went straight to the root of the problem.

And for Toga, I find amazing the fact that she just disappeared after the resolution. She won in some sense because she got to live like she wanted! She was seen, she was loved, she was known!! She is the only winner out of the League of Villains and that's thanks to Ochako.

Is she dead? Is she alive? We don't know because Toga is no longer a villain and she is free from the narrative itself. She haunts Ochako, but she's free to live and be common now. A normal girl.
