In the epic world of My Hero Academia, one can't help but notice the blurring of lines between heroism and villainy, which is brilliantly interwoven through its compelling narrative. The anime presents a deep exploration of the ideologies that govern these two opposing sides, and in doing so, journeys to the gray area. This is extremely evident and significant during My Hero Academia's Paranormal Liberation War Arc, when Twice heartbreakingly sacrifices himself to protect the rest of the League of Villains.
