@hedgemoney You expected an "actual virus" from a fantasy isekai? Forget isekai, I doubt there is a single story in existence with an "actual virus" as protagonist. Your expectations make no sense at all. Bye, nobody cares.
Are traits and personality skills? So I presume there are skills such as "courageous", "clever", "perverted", "treacherous", and "complete idiot" or "hopelessly naive".
