The Toyota minivan debuted in 2001 as the successor to the Town Ace Noah. The previous Town Ace Noah had FR drive, which is a minority of minivans, but the successor Noah uses FF drive and FF-based 4WD, which is more space efficient, and the body platform has been completely renewed accordingly. Despite its seating capacity of up to eight passengers, the Noah is characterised by its relatively compact body, which is easy to manoeuvre. Sales in the Japanese market were extremely strong and the Noah has since established itself as a best-selling car in Japan.

A generic name for a group of games, mainly bullet-hell shooting games, produced by Shanghai Alice Phantom Circle, a private circle run by ZUN. Production began in 1995 and the first game was released in 1996. This is said to be due to the intention of the creator, ZUN, as the character personalities, designs and settings of each work are not necessarily continuous and are not recognised as part of a series. The production, from the programme to the graphics and BGM, is almost solely the work of Shanghai Alice Phantom Band (i.e. ZUN alone). The BGM in particular is highly regarded, and many arrangements have been made by fans. The story and characters are also popular due to the unique worldview set in the imaginary world of Gensougo, which is based on a Japanese motif, the characters' unusual personalities and settings, and the depth of the backstory, and many derivative works (novels, manga, etc.) have been created.

Her sword master is Konpaku Yoki, who is also Yōmu's grandfather. However, he disappeared suddenly in the middle of his teachings, so Yoki is in the midst of her inexperience. If an intruder appears, she immediately slashes at him, whether he is a yokai or a human. Of course, she does not check who she is dealing with. There isn't much that can't be cut!"
