📍 Synopsis

_____ Year 20XX The world was invaded and destroyed by "something" from outer space. Humanity attempted to resist by gathering all available military power, but they were no match for the threat. The war was lost and the world nearly collapsed, but survivors in each country built massive underground facilities isolated from the surface to prepare for the next invasion. There, humanity continued development to achieve victory.

The project was named "Android."

Human-shaped weapons with physical abilities and intelligence far superior to humans, possessing special powers. All that was required of them was strength. To ensure they functioned as weapons for eliminating enemies without hesitation, they underwent thorough adjustments to prevent the development of "emotions" common to living things. However, an unexpected mutation occurred in a certain individual. "Emotions" began to sprout in an android that was supposed to be heartless. He began to shed tears when sad, laugh when happy, care for others, and feel anger on someone else's behalf. Eventually, this mutation spread beyond a single individual, and the weapons created to protect humanity began to possess human hearts. - ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
