Storyline

Gensoukyou, - a magical forest. Alice Margatroid, a wizard who lives in a house in the forest, was checking the forest. A few hours ago, the fairies in the forest began to stir, and at the same time, she began to see monsters, not ghosts, spirits of ghosts, or vengeful spirits, but evil spirits of mountains and rivers. The forest itself is growing and changing at an unthinkable speed. Was this a harbinger of some kind of mutation, or did something cause the forest to change? Before we could find the answer, it suddenly struck. A girl on a huge block of steel. The strange youkai attacks Alice without question. Puzzled, she fought it off, and this time she met a familiar face. To her surprise, it was “something” that was a copy of the Alice of the past. Alice tried to catch the impostor and ask him about his life, but he would not listen to her and she lost him in the end. I'm sure something is going on somewhere I don't know about.... I can't help it. I don't feel good about leaving it alone, so I think I'd better leave this to the anomaly experts instead of going it alone. The mutation expert is Reimu Hakurei, a priestess at Hakurei Shrine who makes her living as a youkai exterminator. Alice went to the eastern shrine to meet her.
