Berserker/Mysterious Heroine X (Alter) from Fate/Grand Order joins the figure world thanks to Sentinel!
She's wearing her scarf over her nose and mouth, although you can remove it and display her without it if you choose.
She's also carrying her Evil Saint Sword Necro Caliber in her right hand. Aside from that and the high boots, she looks more or less like your average schoolgirl, although she's absolutely not to be trifled with!
Height = 22cm approx.
