My Hero Academia is building suspense with Deku relying on Eri as his last hope to defeat All For One. After a failed attempt to save Tenko, Deku wakes up without arms, defenseless against the villain. Eri, with her powerful Rewind Quirk, may be the key to turning the tide in Deku's favor. The creator, Kohei Horikoshi, has hinted at Eri's importance throughout the story, suggesting she could play a crucial role in Deku's recovery. Eri's ability to revert organic matter to a previous state could potentially restore Deku's arms and give him the strength needed to defeat All For One. Despite her young age, Eri has already proven to be a valuable asset to the heroes, showing that anyone can be a hero regardless of their age or abilities. My Hero Academia continues to explore themes of heroism and resilience in the face of adversity.
