“Hourai NEET” (蓬莱ニート), or “NEET Princess” (ニート姫, Nīto-hime), was a derogatory nickname for Kaguya Houraisan from Touhou Project, mischaracterizing her as a Hikikomori or NEET, despite it being an obvious joke when the inverse statement is actually canonical.

The misconception stems from a joke in Touhou Eiyashou where Eirin joked that Kaguya was 'finally' playing outside again in the Barrier Team's Good Ending, which leads to Kaguya pointing out that this was actually Eirin's idea to keep her imprisoned in the first place. For some reason, people decided to run with the idea that she's a slovenly NEET princess who spends her time playing video games on a computer.

In reality, Kaguya mentions several times that she disliked this isolated life, desiring a job to fit in on Earth in the novel version of Touhou Bougetsushou¹⁾ and voicing her boredom in Touhou Eiyashou. Following the incident, she became the Lunar Capital Expo's²⁾ lead organizer, actively socializes, travels to the countryside, attends matches in the Human Village in Touhou Shinkirou, etc.
