Tadayoshi Fujimaki also shared the following message:
“Thank you all for coming to the KILL BLUE stage here at Jump Festa!
Finally—at long last—KILL BLUE is… becoming an anime! Well, saying “at long last” might be a bit of an exaggeration, but…
Yes, it’s becoming an anime!
Is this a little too laid-back? No, this is about right. Because KILL BLUE was always meant to be a light, easy read. Even if you brace yourself… nothing crazy is going to happen. There are no demons, no monsters—none of that. But there’s one thing I really want to point out.
Just because a snack tastes crisp and light doesn’t mean the people who make it whipped it up effortlessly. And KILL BLUE is the same way.
It may feel light and easy to read, but it definitely wasn’t created “effortlessly.” Just look at this amazing staff and cast. Everyone is giving it their all. They’re working with full power to bring you a light, fun KILL BLUE anime.
So if you can approach it with the same kind of excitement as, “Hey, my favorite snack is getting a new flavor next year!” —that level of hype is perfect.
Thanks, and we hope you enjoy the KILL BLUE anime!”
Hiro Kaburagi is the director of the KILL BLUE anime. What’s more, Miho Daidōji is the character designer, and CUE is producing the animation.
The KILL BLUE manga received a new novel adaptation, titled Kill Ao Secret Report (Kill Blue Secret Report), by Kiyoko Hoshi. The novel shipped on December 4 alongside the manga’s 13th and final compiled book volume. Shueisha serialized the KILL BLUE manga in Weekly Shonen Jump.
Lastly, here’s an overview of the series, via Shueisha:
A legendary assassin at 39. Starting over… as a middle schooler.

When he wakes up, the fearsome 39-year-old assassin has been transformed into a 13-year-old boy! Before he can even process what happened, his boss delivers a new order: “In that body, infiltrate a middle school.” What awaits him is an unexpected school life filled with colorful classmates, youthful chaos, and looming danger. Can Jūzō ever return to his original form? Or will the assassins closing in on him end his second life before it even begins!?
