from the previous chapter we see the continuation of the battle between starts & stripes and the shigaraki and all for one fusion. the battle would have ended there because stars and stripes made a rule that if sgigaraki were to move his heart would stop ⛔ but that ended in a massive failure because the person she was fighting was no longer shigaraki but an entirely new personality in conjunction on who he actually was.
shigaraki survived the attack in the previous chapter but in this one starts and stripes was given an opportunity to strike down shigaraki but that would be at the cost of her comrades; she was hesitant then shigaraki jumped and grabbed her face.
