Who Dares Become a Mercenary in a Mecha World?

[No System + No Female Lead + Non-Simulated Aerial Combat + Thrilling Battles + Mecha] You know how it is... There are usually three kinds of people willing to fight and kill in war: Butchers consumed by bloodlust and rage, and heroes hungry for glory and merit. And then there are the mercenaries known as "Hell's Retinue": These are dogs who serve neither medals nor justice, yet they're the most "free and trustworthy" beings in the sky. They come for the bounty, serve whoever pays the highest price, and risk their lives for things worth nothing at all. Their fates are simple: they die in the sky or in the sea, and no one remembers them... In a burning sky, whether soldier, thug, or hunter, there's only one thing to remember: only the strongest can claim honor. I hope you'll enjoy this story.
