'My Hero Academia' draws parallels between characters, including Shigaraki and Eri. Both children accidentally used their quirks to destroy their families, falling into the hands of villains who exploited their powers. Eri's rescue by heroes contrasts with Tenko's abandonment, showing how Hero Society can save children like her. Eri is adopted by Aizawa, learning to control her quirk in a loving environment. In contrast, Tenko becomes Shigaraki, manipulated by All for One in a twisted form of care. Eri's story highlights the impact of kindness and rescue, preventing her from falling down Shigaraki's path. This connection enhances the series and explores the contrast between innocence and evil. 'My Hero Academia' follows Deku, a quirkless boy who inherits a powerful quirk and trains to become a hero at UA with his classmates.
