Yui Ishikawa, the voice of Mikasa Ackermann in the Attack on Titan anime, covered the anime’s “Akuma no Ko” ending theme song on the CrosSing channel. The song, originally by Ai Higuchi, was used in the Attack on Titan: Final Season Part 2.
Higuchi returned for the anime’s final season with “See You Later.” This song was used as the ending theme song for the episodic version of the two specials that completed the adaptation.
In addition to voicing Mikasa, Yui Ishikawa was also featured on Attack on Titan’s soundtrack on the “13 no Fuyu” by Linked Horizon. The song was used as the first half of the “Nisen-nen… Moshi Aru… Niman-nen Ato no Kimi e” theme song, used in the final special.
The “Akuma no Ko” song was writted by Ai Higuchi and features strong anti-war themes. It has a special music video with scenes from the anime:
