On June 3, 2022, LINE Manga announced that Boichi and Youn In-Wan would be creating a webtoon called Superstring. The plot follows a young man struggling alone to protect his family while heroes from various universes wage war on Earth.

The Superstring release date will be in 2023 on the WEBTOON platform. Boichi will be doing the art while Youn is in charge of the writing.

Boichi is best known for his work on Dr. Stone, Sun-Ken Rock, and Origin. Youn In-Wan is currently the Chief Creative Officer of LINE Digital Frontier Co.

Youn debuted in 1999 with his manwha Bom, and his most notable work is Blade of the Phantom Master. This creative duo hopes to use Superstring to strengthen WEBTOON’s position in the global market so it can reach as many people as possible.

What’s a manwha?

Manwha is the Korean term for comics and print cartoons, but the term is also applied to South Korean comics. Manwha plays a massive part in Korean culture and is growing more popular thanks to various titles getting anime adaptations, live-action films, and tv series.

Many manwha is being translated on sites like WEBTOON, TappyToon, and Manta. The most significant difference between manwha and manga is that manwha are full-color, whereas manga is primarily black and white.

Though an official lineup hasn’t been revealed, if you look at the bottom right corner of the Superstring art, you can see the YLAB logo. YLAB works with many companies involved with films, comics, tv series, and more to create high-quality manwha.

And if you visit the YLAB site, you can see a list under Superstring and a variety of manwhas with a timeline. Are these the heroes that will wage war in Boichi’s and Youn’s latest work?
