Sentenced to Be a Hero may be a fantasy series on the surface, but one of its earliest sparks came from a very different place: Ace Combat 7.
In a new interview after the anime's first season wrapped, author Rocket Shokai and illustrator Mephisto looked back on how the series grew from a light novel into a larger franchise. Since launching in 2020, Sentenced to Be a Hero has reached eight published volumes, picked up a manga adaptation, and made the jump to anime through Studio KAI.
According to Shokai, the seed for the story came from the penal unit sections in Ace Combat 7. He said those parts of the game were especially compelling, and they made him want to explore the same kind of setup in more depth, but through a fantasy world instead of a military flight game.
That detail will probably click with a lot of readers in Malaysia and across SEA. Plenty of anime fans here also grew up on console and PC games, so a story built from that crossover point, war drama structure on one side, fantasy on the other, makes a lot of sense. It helps explain why Sentenced to Be a Hero feels a bit different from a standard heroic power fantasy.
Shokai also spoke about how his working relationship with Mephisto changed over time. Early on, he found it hard to clearly communicate what he wanted from the character art. That improved once both creators started talking directly and discovered they shared similar tastes and influences. From there, the visual side became easier to align.
Mephisto said the process usually starts with what is written in the novel, but he allows himself a lot of room to interpret designs in his own way. Because Shokai keeps visual direction fairly light, Mephisto has been able to work quite freely. In his view, the "distinctive" feel of the characters mostly comes from his own drawing instincts and the works that shaped him over the years.
The anime adaptation also had stronger creator involvement than some fans might expect. Shokai said he worked closely on major production elements including the script, backgrounds, props, and even the in-world technology. One part he particularly remembered was creating crests and house mottos. For him, seeing the story transformed through animation, voice acting, and music continues to be surprising, especially when it goes beyond what he first imagined.
Mephisto, meanwhile, supervised much of the visual side. He made design changes where needed so characters would better fit the world, and one noticeable choice was giving characters more coverage in their outfits. His reasoning was simple: if the setting is cold, it would look strange for people to be showing too much skin.
One of the series' most interesting ideas is that severe injuries can be undone, but not without psychological consequences. Shokai traced that concept back to a scene from George R. R. Martin's A Song of Ice and Fire, where life remains, but nearly everything that makes life meaningful has been stripped away. He wanted to capture that same emotional tension, the idea that survival alone is not always enough.
That also connects to how he approaches the series overall. Shokai said he wanted to combine the scale of a war chronicle with the energy of comedic rogues moving through a tragic world. In his view, the harsher the setting becomes, the more clearly the protagonist stands out by pushing through despair. Mephisto added that realism comes from drawing a broad range of people, not just idealised faces, and making even attractive characters look distinct.
Asked what they are most proud of, Shokai pointed to the storylines of Lideo Sodrick and the Spriggan within the material adapted into the anime. Mephisto named Rhyno as his personal favourite, while also highlighting the individuality expressed in the designs for Xylo, Teoritta, Dotta, and Rhyno.
For anime fans in this region, especially those who like darker fantasy with a strong visual identity, this interview makes one thing clear: Sentenced to Be a Hero was built with a very specific creative vision, and both its writer and illustrator have stayed closely involved as it expanded.
