The first week's journey has carried the children of Nagakushi village out of the mountains into unfamiliar territory, and the second week pushes them further still. The oni who stole the elderly couple's souls are spread across the land, and fighting through them reveals something the children did not expect: they are effective. Trained only by the necessity of surviving, both the boy and the girl develop in combat and in confidence as the week advances. What they cannot yet see is why the dragon sent the oni outward rather than keeping them close — and what the dragon actually wants. Week two of BS Shin Onigashima deepens the dungeon structure, adds new enemies and terrain, and brings the western capital one chapter closer.
