The Toyota minivan debuted in 2001 as the successor to the Town Ace Noah. While the previous generation Town Ace Noah had FR drive, which is a minority among minivans, the successor Noah adopted FF drive and FF-based 4WD, which are more space efficient, and the platform of the vehicle body was completely renewed accordingly. The new Noah is characterized by a relatively compact body that is easy to maneuver despite its seating capacity for up to eight passengers. Sales in the Japanese market were extremely strong, and the Noah has since established itself as a best-selling car in Japan.

This is the generic name for a group of games, mainly bullet-hell shooting games, produced by ZUN's private circle "Team Shanghai Alice". Production of the series began in 1995, and the first game was released in 1996. This is said to be due to the intention of ZUN, the creator of the series, as the character personalities, designs, and settings of each work are not necessarily consecutive, and the series is not recognized as a series. The production, from the program to the graphics and BGM, is almost solely the work of Team Shanghai Alice (i.e., ZUN alone). The BGM in particular is highly acclaimed, and many arrangements have been created by fans. The unique worldview set in the imaginary world of "Gensoukyo," a world based on a Japanese motif, the characters with unusual personalities and settings, and the depth of the backstory make the story and characters very popular, and many derivative works (novels, manga, etc.) have also been created.

She makes her first appearance as a boss in Stage 5 of Touhou Yoyomu. She is a half-human, half-ghost , and her human body is clad in ghosts. Her lifespan is much longer than that of a human, and her normal temperature is slightly lower than that of a normal person. She is the swordsmith instructor to her master, Saigyoji Yūyūko, as well as the gardener who lives in Hakutama-ro, where she practices swordsmanship daily. Her sword master is KONPAKU YOKI, who is also Yumu's grandfather. However, he disappeared suddenly in the middle of his teachings, so Yoki is in the midst of her inexperience. Whenever an intruder appears, she immediately slashes at him, whether he is a yokai or a human. Of course, she never checks who she is dealing with. There is nothing she rarely can't cut! Her title is "swordsmanship instructor and gardener," and he is not in charge of the general household affairs of Hakutama-ro as is often depicted in secondary works (preparing meals, etc., is the job of the other ghosts who live in Hakutama-ro). According to the book "Bunkacho," she has never received a vacation or a salary.
