One more day!
Those are two different girls. The first one is from Akiba's Trip 2. The second one is anime original.
I spent 600 hours on gameplay and 600 hours on loading screens and yet they're not giving me my beloved perfectly-dressed 100% buffed fully-equipped battle partners from the original game. They instead made these crappy new characters we don't know shit about.
So, seeing that that's obviously that fucking finn Kätikönen Räikköwhätever working in motherfucking maidreamin, does she joins Mogra's cult of absolute retards later chronologically speaking and assuming the second game is actually set after the first one even if it was clearly a spin-off or did they just put her in there because why the fuck not?
Still mad she doesn't have a route. She's actually pretty cute.
