巨大妖怪伝説の章

This is a short episode that narrates the events of Touhou Hisoutensoku. The episode begins with Daiyousei asking for help from Alice Margatroid to find Cirno, who left in search of the giant youkai. After talking to Sanae Kochiya, Marisa and Reimu; Cirno goes to the Underground Geyser Center during the search, only to find Utsuho Reiuji and be confronted by her. Cirno is saved by Daiyousei from Utsuho's final attack. The fight ends when Suwako Moriya and Alice arrive on the scene, and Utsuho is reprimanded by Suwako. In the end it is revealed that everything was a misunderstanding, and what Cirno actually saw was Alice's Goliath Doll. Meiling is seen sleeping the whole episode.

在滿福神社釋出此集之前，觀眾根據先前發行的PV或是每集完全不可信的結尾彩蛋，紛紛猜測第七話的內容。然而出乎意料的是，本片取材竟是東方格鬥遊戲《東方非想天則 ～ 追尋特大型人偶之謎》。之前已有大量戲份的琪露諾升格成主角，令人不得不吐槽琪露諾就是滿福神社的“親女兒”。情節大體遵循琪露諾和紅美鈴的歷險線路。開場動畫依然是PV「色は匂へど散りぬるを」。 琪露諾一日發現一個人形巨物，認為此物即是“大太法師（日本傳說中的巨人，多地留有他的遺蹟）”。一番找尋之後的冰之妖精最終在地底遭遇靈烏路空幻想鄉智力的巔峰對決就此上演！…… 片尾曲為senya演唱的「可能性の化身」（原曲：「我們的非想天則」）。
