this article may contain major plot or ending details
As a whole, the three haven’t had very many interactions, especially due of Himiko’s being a villain, while Izuku and Ochako are heroes, which make them from different bands and so being enemies. Though, Ochako and Toga had discussed about him several times like in the Forest Training Camp Arc.
In the following arc, Tsuyu and Ochako get attacked by Toga while both girls were doing their training. Ochako then manages to attack Toga and immobilize her for a moment by standing on her back and then Toga asks Ochako if she had someone she liked and that if she wanted to be like certain person. Ochako then remembers on what she said before; "I'll win! I'll win and be like Deku, too!" as it is shown that the person who Ochako liked was no one else but Izuku. Toga then realizes she was right and continues by telling Ochako that she could tell, because afterall Ochako was a "maiden" just like Himiko. Toga, while smiling and blushing, then tells Ochako that it was only natural on liking someone, since she'll end up on wearing the same things like the person they like but in the end it wouldn't be enough and it cannot be helped. After Toga ends her conversation with Ochako, she attacks her by absorbing some of Ochako's blood for then escaping the place, leaving behind both Ochako and Tsuyu injured.
Ochako and Toga then reunite again in the Paranormal Liberation War Arc, Toga then tells Ochako while being hidden that she wanted to talk with Izuku, and then points out that he's always with injuries and blood which made him "cool" for Toga. During their fight, Toga takes something from Ochako (an All Might keychain) and Ochako tells that it was something important to her. Toga then points out that she and her were the same, since both liked the same person (Izuku), and Toga said that she knew it all along, and again tells her that they were really alike. After Tsuyu went to save Ochako, Toga leaves the place and leaves the keychain behind so Ochako would have it back, and as soon as she left, she said that she finally got her "answer" from Ochako while some tears were going out of her eyes.
It is rather a rarepair in the fandom, due on Himiko and Izuku along with Ochako are enemies. People would prefer ship Izuku with Ochako and in other ocassions they would prefer shipping both Uraraka and Toga together and ship Midoriya with anyone else like Todoroki or Bakugo. Nevertheless, the ship sailed as result on the love triangle that are between the three, though Izuku had never confirmed on having a crush in whether Ochako or Toga. The polyship has a less amount of followers as it's overshadowed by other much popular polyships like TodoBakuDeku and HimiTsuChako. The small fanbase of the polyship that like shipping Izuku with both Ochako and Toga at the same time created the love triangle with the three of them.
Some fan theories say that Ochako could be the traitor of U.A, and that she could be secretly working with Toga and LoV and pretending on being a student wanting to become a hero. However Ochako hadn't shown signs on being on Toga's side due she's seen on hating the league, and her wish on becoming someone better to help her parents.
