Hara Para!! - Swan Nakadashi Paradise

Your ultimate goal: journey to the farthest corners of the universe to find the cure that will save humanity from extinction.

It is 1642, the final years of the Ming Dynasty. The scholar Fang Zhiyou loses his mind to grief when his childhood love—the celebrated Yangzhou courtesan Su Lianyan—is found drowned. Convinced that all men are beasts, he numbs himself with wine, his memories shattered.
Three years later, drunk and broken, Fang Zhiyou awakens to a nightmare: he is trapped inside Lion Camel Kingdom, the world of his own macabre writings. Demon soldiers have breached the gates. As the city burns with slaughter, pillage, and flame, a man with no will to live finds a reason to survive: a feral young girl called Little Yan, whose face is a ghostly echo of Su Lianyan. He makes a desperate vow—to keep her alive until the massacre ends.
As they flee through the charnel house of his own creation, fragments of his past resurface, blurring sanity into madness. But the truth, when it comes, will offer no escape from his destiny...

In the near future, humanity has achieved remarkable progress with the discovery of infinite energy called "Akasha Particles." However, this advancement also brought about the emergence of "Gigantic Beasts," which dethroned humans from the top of the ecological hierarchy. The survival of the displaced humans now depends on large humanoid weapons called "Exos" and the "Mercenaries" who pilot them.
The protagonist, a former mercenary, lost the ability to use Akasha Particles due to a past accident. Unable to pilot an Exo, he considers himself a "defective" and wanders aimlessly, leading a reclusive life.
One day, he meets a young girl aspiring to be an Exo mechanic. She inherited her late mother's designs and built an Exo that is scorned as an "antique" by others because it doesn't use Akasha Particles, a stark contrast to the technology of their time.
A defective mercenary who can't use particles and an antique Exo that doesn't rely on them—when these two meet, the wheels of their story slowly begin to turn.
"―――Launch, Cuniculus."
