In case you didn’t know, Sonico is the mascot of Nitroplus, a company that makes visual novels and porn games (a.k.a. eroge). It must not take much to garner a following in Japan, because the explosion of Sonico’s popularity is inexplicable otherwise. Good Smile Company is making a Nendoroid of her, and in the figure world that’s the equivalent of getting your own HBO series.
Fate/Stay Night the anime was, to me, a bunch of cool ideas ruined by a bumbling dumb hero protagonist and desperately contrived harem cliches. But I’m grateful that the franchise exists and achieved some popularity, because it brought us this Saber figure.
