俺の仕事は魔物掃除です

Alex takes Silver Oak's night watchman job—100% mortality—to pay bills. He treats horrors like cleaning: fists, disinfectant, tape. Lily warns him; Leah reveals Lily was sacrificed as the abyss seal's anchor. Seal collapses; Alex reinforces with tape—only to learn his entity was a decoy. The real monster hides among teachers. Sky cracks, eyes loom. Alex asks: how much overtime pay?
