The series received a TV anime adaptation by Telecom Animations. Crunchyroll and WEBTOON partnered last year to create anime series for Tower of God, The God of High School, and Noblesse.
Crunchyroll is streaming the anime series and describes the show as:
Reach the top, and everything will be yours. At the top of the tower exists everything in this world, and all of it can be yours. You can become a god. This is the story of the beginning and the end of Rachel, the girl who climbed the tower so she could see the stars, and Bam, the boy who needed nothing but her.
