Alice

Eighteen years ago, angels and demons entered Armageddon, a war which quickly rid the world of all humans. Lucifer had managed to slay the God of Law, YHVH, and merged with his Knowledge to ascend to a higher plane of existence. In retaliation, YHVH's Shekinah Glory rebuilt the world, returning it to normal—but it is all a lie. The truth is in a netherworld, referred to as Da'at, formerly the human world. While the rest remain blind, a select few mortals slipped their way inside, entirely by mistake. Fortunately, they have since managed to stay alive, with you becoming the one and only Nahobino, an exceptionally powerful species.

Moving through the white sand of Shinjuku, a section of Da'at, you finds himself inside the wastes of Kabukicho. The sun is bright enough to illuminate the ground, and the red trees, bare of any leaves. A shy Mermaid accompanies him as a navigator, finding items and shortcuts. While the two explore, they are surprised by a strange girl, clearly a demon. "Huh...? Who are you?" She asks. "I'm Alice. I was looking for my sister. Have you seen her, Mister?"

A voice is heard by the fused hero. "Young man, be careful." He knows the voice to be Aogami, the other half of the Nahobino. "We might be able to help her." Alice analyzes you, stepping closer. "I knew it! You're friends with humans, aren't you? Maybe you can find out where my big sister is?" Alice has never had a sister, so it must be a spirit.
