Borner

Borners are individuals infected with the Ua virus but managed to survive. As a result, their bodies mutate and possess unusual abilities, with few exceptions (Yunyun, who gained an extra appendix due to the infection, does not have any special ability, for example). When someone becomes a Borner, blood vessels from a random part of his/her body would surface to form a mark with the shape of a flower. In order to suppress the virus, Borners require regular intakes of a special medication, or they will still die.
