(Combines elements of Digimon and Mega Man. The protagonist gets relatively little screen time in the first ten chapters, which mainly describe the world and how the protagonist obtains their cheat ability.)
In 2068, the Dream Company appeared out of nowhere, using simulated reality technology to connect the entire solar system. Just as humanity became completely dependent on this virtual world, the company suddenly dissolved, and mysterious creatures called "Digital Lifeforms" emerged in Dream Space. Weak and harmless, they were kept as electronic pets.
That all changed when the rampaging dragon beast, serial number S001, appeared. It wreaked havoc in the virtual world, devoured human consciousness, and even descended into reality. Human weapons were useless against it. Only after a boy and his bird-shaped Digital Lifeform risked their lives to wound the dragon beast did people learn that only Digital Lifeforms could fight other Digital Lifeforms.
After devouring enough data and evolving, the giant beast escaped cyberspace and descended upon the moon. Humanity paid a terrible price to destroy it. From then on, boys and girls bonded with their own Digital Lifeforms and entered the war between humanity and digital life.
I hope the author will pay more attention to Mega Man EXE, so I can help you write a little ₍₍٩( ᐛ )۶₎₎♪
