Izuku Midoriya, Ochaco Uraraka & Tsuyu Asui vs. Himiko Toga

Deku, Uravity & Froppy vs. Himiko is a battle taken place during the Second War as Heroes Deku, Uravity, and Froppy face against the Villain Himiko Toga.

Prologue
The Heroes commence their plan to defeat the Paranormal Liberation Front once and for all. After luring All For One and his army out, the Heroes activate the "Troy" defense system, causing metal cages to rise from the ground and surround themselves around the villains. While they are able to break free fairly quickly, the couple seconds gives the Heroes just enough time to shove each of the villains into individual Warp Gates, in order to break the villain force into smaller groups and push them into the respective Warp Gates to split them up all across Japan.

Uravity and Froppy lead the charge in shoving Himiko through one Warp Gate, taking them and several accompanying villains, as well as two Near High-End Nomus, to Okuto Island, a resort island 200km off the mainland. They are specifically sent to Okuto Aquarium, run by Gang Orca, with the plan of isolating Himiko somewhere where she is unable to escape.

Deku, on the other hand, is part of the hero team in charge of fighting exclusively against Tomura Shigaraki at U.A., now converted into a flying fortress specifically designed to neutralize his powers. Everything seems to go well, until Himiko manages to catch him off guard with one of her tubs from her Blood Sucking Machine, dragging him into her portal before it closes. This causes Deku to end up at Okuto Aquarium, hundreds of miles from where he should be, much to the shock and confusion of his allies in both places.

Battle
The battle between the Heroes and the Villains erupt into chaos, specifically thanks to the Near High-Ends causing shockwaves that split up many of the combatants. Deku and Uravity end up being separated from Froppy, where Deku tries to get into contact with Eraser Head to warp him back. When he gets word that he can't due to their current fight and needs to make it there on his own, he tells Uravity he has to leave.

However, before he can act, Himiko suddenly jumps toward him with her knives, yelling that she loves him and not to go. Deku is still surprised that she's once again able to catch him off guard, as even while charging at him to attack, his Danger Sense isn't activating, not recognizing the actions as "danger" due to her feelings. After evading, he asks what she wants, and Himiko casually states that she wants him to be her boyfriend.

The revelation catches Deku and Uravity off guard, with the former freaking out and asking what she's talking about. Himiko continues to confess that she's felt this way ever since they first met, since he was so beaten up and looked exactly like her first crush, her face twisting saying she wants to suck his blood and become him. Deku stammers asking if being a couple means doing stuff like going on dates and holding hands, while Himiko states that being a couple to her means being one and the same.

As another shockwave from the Nomu occurs, Himiko asks Deku what he wants to do with her, which Uravity recognizes as the same question she asked her during the Paranormal Liberation War. When Himiko once again hides her presence after the shockwave subsides, preparing to come in for an attack, Deku says that he too wanted to become like All Might, and that he understands her, and how fulfilling it feels. However, he proceeds to say he could never share the same heart and mind as him or think about hurting the ones he love. Hearing this causes Himiko to think back to the words of her parents, Curious, and Uravity, and her face twists once again.

She says that Deku and Uravity are both the same, just like her parents, stating that they think only Heroes and those they protect count as real people, which is why they’re destined to be apart. As Deku's Danger Sense kicks in again, Himiko runs at him and Uravity with her knives and whips, with Deku dodging while Uravity grabs ahold of her. Uravity says she’s been thinking hard about her even since their fight, while Himiko claims she hasn’t been on her mind anymore, and that she’s through thinking of the both of them; if the world rejected her, she’s entitled to do the same.

Uravity’s distracted by some of her whips coming from behind, giving Himiko the opportunity to stab her in the back, declaring she’s sad since they both felt the same way about the same boy. Just as this happens, Deku manages to grab onto Himiko with Blackwhip, who is promptly kicked and pushed away by Froppy. Uravity says she only got a grazed cut, but adds they need to get the knife back, since her blood is on it. Froppy turns to Deku and tells him to leave now as it’s not the place to talk about romance, and to rely on Uravity, who has the most experience dealing with her.

Uravity, with a smile, confidently tells Deku that she will handle this and that he has to deal with Tomura, recalling their conversation from earlier about them both wanting to understand their antagonists. Deku understands, and just as Himiko prepares to get up saying, that it’s so hard to live as her full of love, Uravity yells at Deku to run, who speeds away from the aquarium.

Aftermath
Deku uses a combination of Float, Fa Jin, and his Air Force to blast away from Okuto Island across the ocean toward Tomura's location. He's disappointed with himself he is unable to go faster, as the Second User of One For All reminds him not to attempt to use his Meta Ability, as it can only be used as a last resort. He tells him to believe in his friends, who are all out there for their own reasons, and to focus on his own battle.

Meanwhile back on the island, Uravity and Froppy note that Deku’s gone, with the latter thinking about how she couldn't stand the thought of her friend's secret being revealed like that. Himiko tells the girls she’s had enough and that she’s ready to be who she wants to be, while caressing her pouch thinking about Twice. Himiko declares she has no need for Heroes, while Uravity declares she will also live the way that's right for her, preparing to restart their battle.
