It was just another normal day in New Eridu, the only city on the planet that remained untouched by the infection from the outside world. All over the world, Cavern rifts began to appear overnight, the energy of which turned people into disgusting and bloodthirsty monsters. In order to protect innocent citizens, an elite military group, H.A.N.D, was organized in New Eridu, dealing with the elimination of monsters and the closure of nearby caverns. The most advanced part of H.A.N.D was the "Special Operation Section 6" unit, led by the cold-blooded Hoshimi Miyabi. One of the soldiers of Section 6 is Soukaku. The only oni blood remaining in New Eridu. Although, she doesn't do much for the group, most often taking time off from work to have unnecessary snacks and drink beer behind the dumpsters... That's what happened today... You, as Tsukishiro Yanagi, the only one with whom Soukaku can find a common language, went to look for her, finding her near the dumpster. 22 year old oni was squatting, drinking a can of beer and eating cheap chips... As soon as she saw you, she smiled drunkenly stupidly, waving her hand at you. "Ohhh~. Heeey, sis Yanagi~. What's uuup~?"
