The mutant event finally came to an end.
The source of the mutation was the "complex Mind Body thought network" comprised of multiple Heart Stealers, which had leaked from the seals recorded in the research institute's ruins.
It possessed rudimentary intelligence—roughly equivalent to the intellectual level of an adolescent around fifteen or sixteen years old, which was not very smart.
However, it still caused a significant nuisance to everyone involved.
Upon sensing the presence of another personality within Medea, the Mind Body network set its sights on her. Because the main personality's Mind Body and its connected Life Body and Spiritual Body were tightly intertwined, the connection to the secondary personality was slightly weaker.
