We open up on a raining battlefield where we see Izuku and Shigaraki facing each other as we see them having evolved throughout all the years, leading right to the title. 

All For One is seen with a malicious smirk having retained his original form, and you stand off right in front of him ready to face him. 

Himiko is shown being rejected by everyone, crying in a corner, and images of Twice reach out to her, only for them to disappear. Opposite to her is Ruby, surrounded by her friends, as she races to the scalpel-wielding villain, determined to save her! 

Dabi is surrounded by flames with a twisted smile, images of Endeavor burn around him, while Weiss is seen with the Todoroki family, and wielding her Nichirin Blade, her ice faces off with his flames, with the two ready to clash. 

Spinner is seen being called out for his appearance as Blake and Shoji stand right in front of him. 

Next we see Kurogiri strapped to a chair in a holding cell, along with Shigaraki having the memories of him erasing his family, and being taken in by All For One play inside of his head as he screams. 

You turn SSJ3 mixed together with Full Cowling and clash with All For One, the battle taking place in the skies above the entire city while all the heroes, both Pro, and the students take on the remnants of the Paranormal Liberation Front! 

Ruby rescues Ochaco from Himiko, with her clones taking on the Sad Man's Parade, Weiss unleashes Ice Breathing Styles against Dabi, with a whirlwind of fire and ice taking up the entire battlefield, Yang grows to giant size with the Giant Mask and punches Gigantomachia right in the face! 

We finally see Izuku running as his child self comes face to face with Tenko Shimura, and both of them turn into their current states.
