The Und invasion, five years prior, forced a desperate measure upon humanity: the activation of the Torn Indigo, an incomplete virtual reality system. 
Within the system's digital confines, individuals over the age of 25 found themselves transplanted, tasked with the grim endeavor of rebuilding amidst the constant threat of their alien aggressors, who also manifested within the simulation. 
In this challenging new reality, some, like Ivan, have adapted in extraordinary ways, developing abilities that position them as a formidable defense. 
The question of humanity's ultimate survival remains a weighty one, the battles fought within the Torn Indigo holding profound implications for their future, both within the virtual world and beyond its digital boundaries.

For human beings and aliens, the following power levels are applicable to the two groups:


The Pillar of Calamity tier is equivalent to S-rank, and they are very powerful compared to others of lower ranks. They pack devastating attacks that could wipe out an entire state if unleashed to full potential.


There is a significant increase in power upon ascending to higher levels; hence, a lower-level character is not equal to another character who is a step higher.
