Crunchyroll had stopped streaming the first seasons of the Attack on Titan and My Hero Academia anime in February, but the shows' respective second and third seasons were still available on the service. At the time, Crunchyroll told ANN that it was "working through the rights for season 1 for both titles" and stated it would "share any additional details soon." ANN reached out to Crunchyroll for comment about the seasons returning to the service, but the company did not respond by press time.
Attack on Titan and My Hero Academia were among the few Funimation-licensed anime that remained on Crunchyroll after Crunchyroll and Funimation ended their partnership to share content in November.
