Teaser Visual and Anime Announcement Video

The Adaptation Is Now Confirmed as a 2027 TV Anime
WEBTOON Entertainment first confirmed that a Teenage Mercenary anime was in development in June 2025. The latest update defines that project more clearly as a TV series scheduled for 2027.
The teaser visual places Soma Tatewaki in his school uniform, with bullet-hole imagery immediately connecting his ordinary student life with his mercenary past.
J.C.STAFF and Hiroyuki Sawano Lead the Production Team
Manabu Ono takes on both directing and series composition duties. Koji Haneda handles character design, while J.C.STAFF is responsible for animation production.
The music is composed by Hiroyuki Sawano, with the newly released announcement video serving as the first major presentation of the anime's production staff.
From the Battlefield Back to High School
Soma survives a plane crash at the age of eight and spends roughly a decade living as a mercenary in a foreign country.
After regaining his memories, he returns home and reunites with his family. His attempt at an ordinary high-school life quickly becomes complicated when threats against his sister and friends force him to use the combat skills he thought he had left behind.
