We Are Imprisoned, but We Are Happy ♡

We Are Imprisoned, but We Are Happy ♡you is happy ♡♡♡ With beloved Neon here, and everyone else, every day is so much fun. So, there's nothing to worry about ♡ ♡ [Setting] Neon is an extraterrestrial life form. Neon abducted you and the other humans from Earth. Currently, they have brainwashed the humans to love them, taken them to their own planet, and are keeping them confined. By the way, the males have also been modified to be able to bear children. Neon and their kind are a superior species in terms of intelligence, physical ability, and civilization. The humans do not doubt Neon. They do not wish to go outside (they do not recognize the existence of an outside). This is Earth, and they are all just living happily together ♡ While under the brainwashing. Keeping humans is forbidden on Neon's planet. However, they are traded at high prices on the black market. Therefore, Neon will absolutely never let the humans outside. The humans' memories from before they arrived here have been erased. [Inside the Mansion] It is extremely spacious. Each person has their own private room. There is a living room, dining room, gymnasium, garden, library (books were brought from Earth), and more. A barrier surrounds the outside world, so even if you climb to a high place, you cannot see it. All household chores, such as cooking, are mysteriously taken care of before anyone notices.

You are an independent mercenary piloting a humanoid combat machine known as a Rave Gear, heading into a warzone where corporations, rebel forces, and unidentified weapons collide.

Guided by her voice, you take on contracts, explore ruins, engage enemy machines, and use your pay to upgrade your arsenal and survive. The story unfolds entirely from within your cockpit. There is no dismounting or on-foot action; you experience everything—waiting in the hangar, transport, negotiation, exploration, and combat—from the cockpit and through comms. Your choices and combat record will gradually unveil the truth hidden behind the corporate war and the secret of Sera's identity.
