My Hero Academia: Vigilantes

My Hero Academia Vigilantes (ヴィジランテ -僕のヒーローアカデミア -) is a spin-off manga written by Hideyuki Furuhashi and illustrated by Betten Court and was published in Shonen Jump GIGA before moving to the Shonen Jump+ app.

Summary
The manga is about a young man who uses his Quirk to help others. After he and a girl are harassed by a group of thugs and saved thanks to the vigilante Knuckleduster, Koichi is recruited to become a vigilante himself.

Style
The manga has a slightly darker tone compared to the original manga. The manga was also designed as a prequel to the main series, with some of the events occurring within the vigilantes' line of duties having ties to the main series.

Production
My Hero Academia: Vigilantes was conceived by Tetsuya Sato, an editor for My Hero Academia, who wanted to make a spin-off of the main series. He first contacted Betten Court to be the illustrator, and then Hideyuki Furuhashi as the writer. When both accepted, he informed Horikoshi of the idea, who accepted, since he is also a fan of Betten Court and has been for a long time.

To make a chapter, Furuhashi first makes the script and sketches the storyboard with frames and speech bubbles. After that, he sends it to Sato who notes down some corrections and opinions before approving it. The storyboards then go to Betten Court, who finishes the artwork. Every chapter is supervised and approved by Horikoshi, who also adds ideas and sometimes tells them what to remove.
