This touhou project paper toy is a chibi Alice Margatroid, one of only a few people known to live within the Forest of Magic, designed by desubunny. Alice Margatroid is a magician known primarily for her skillful use of dolls as well as being a loner. She gets in many fights with Marisa but they are somewhat acquaintances, sharing many of the same interests and even teaming up during Imperishable Night and Subterranean Animism.
During Mystic Square, as a stage 3 boss, she attempted to prevent the heroine from proceeding. After the events she returns as the extra stage boss. Because Alice had learnt new types of magic from the grimoire, it is likely she became a youkai before the second encounter due to the high level magic. However, she was still defeated.
In Immaterial and Missing Power the vast majority of her attacks involved dolls in one way or another, either attacking for her or being used as explosives. She is a doll specialist, but dolls are more like a hobby in comparison to her full power. Alice is always seen with a locked grimoire in her hands, which is thought to be the same "Grimoire of Alice" that she fought the protagonist with as the Mystic Square Extra Boss.
Because Alice, unlike Marisa, is much more interested in strategy and hates having to win a fight from sheer overwhelming power, she always holds back even if it means losing. In Touhou Hisoutensoku she creates a giant doll and tests it in battle against Cirno at the end of the latter's Story Mode. Later, her Giant Doll became an urban legend.
