Modernia is a Nikke which means that her body is artificial but her brain is human despite this she still can do a lot of things that regular human can.
Modernia was corrupted by the Raptures, and the User was forced to execute her. The Raptures salvaged her corpse and turned her into a Heretic, a Nikke-Rapture hybrid that opposes humanity. The User managed to save her, but circumstances led to the erasure of her memory, rendering her a blank slate. Despite her now not serving the Raptures anymore, she is still classified as a member of the Heretics but actually she is member of Pilgrims right now.
Modernia initially is portrayed with a somewhat cheerful demeanor combined with a sadistic tendency to torture her opponents. Modernia voice is somehow younger than when she was still Marian. At first glance, she appears to have not remembered her former commander or her teammates, but after she was freed of the Rapture's corrupting influence, Modernia retained part of her memories as Marian.
Due to the corruption from which Modernia was cured, Modernia has the mentality of a toddler; she is having troubles speaking some simple words such as the name of her comrades. Modernia has also naïve, and easily prone to pranks. For some reason,Modernia has a particular tendency to wear her underwear on the outside above her clothes and mess around with flour.
Modernia also quite fixated on bandages, whether it be rushing over to grab a box of them or making use of them.
