Akuma no Ko, meaning Child of the Devil, was performed by Ai Higuchi as the ending theme for Attack on Titan The Final Season Part 2 in 2022. Its lyrics reflect Eren Yeager's inner conflict and the burden he carries, which helped the song resonate beyond the episodes it closed. Fans shared short excerpts across video platforms for AMVs and tributes, and the title became a search shorthand for that somber ending mood. It remains popular because it captures the series' tragic final arc in seconds.
