The Webtoon written and drawn by artist Lee Jong-hwi or most commonly known as SIU is set to broadcast from this Spring onward. The story sets around a boy by the name Twenty-Fifth Baam whose friend Rachel aims to climb all the way to the top of a mysterious Tower. The series has been on-going since 2010 with a weekly release divided into seasons. It has now boasted almost 4.5 billion views worldwide. Currently, it is at season 3. More can be found here.
The announcement was made along with a visual teaser:
The visual teaser (as the above) depicts the two main characters of the series, Baam and Rachel facing each other. Behind them is what seems to be the entrance to the tower.
Some comments from the author, SIU:
This is SIU, the original author of Tower of God.
When I was young, I had thought that flying shoes would be made available in 2020.
It is 2020, and I still don’t have flying shoes. Tower of God has been serialized for over 20 years via NAVER WEBTOON (Line Manga) and now the series is confirmed to be animated. The opportunity has finally come for many people to watch.
The year 2020 was a really unexpected year.
I hope this Anime to everyone, will bring more fun than flying shoes.
With the regulars and irregulars together enter the tower, please enjoy the heart throbbing adventure to the fullest.
