This page lists characters who were given some significance within the Touhou series, but not given a name within the canon or fanon. Most of these characters are featured in the PC-98 games.
Red Yin-Yang Tank
Before the Flower Tank, this tank attacked Reimu and Genji on the first stage of Story of Eastern Wonderland. Since Rika said that everything on the first stage was built by her, this tank is obviously hers.
Nameless Midboss Youkai
This character attacked Reimu in the beginning of Story of Eastern Wonderland's second stage. Her species is thought to be a Youkai. Her appearance somewhat resembles Marisa's when she had red hair. Her appearance also is similar to Kotohime
These magical tools attacked Reimu and Genji earlier in the third stage of Story of Eastern Wonderland. Just what they are and who created them are unknown.
Five Magic Stones
As the Five Magic Stones have no profile, no official names, and exchange no dialogue with Reimu, nothing is known about them. It is unclear if they are even living beings, actual stones, or some kind of machine.
Nameless Midboss Angel
This character attacked Reimu twice in Story of Eastern Wonderland's fourth stage. Since she has angel-like wings and holy attire, it is a possibility she is an angel. Her appearance somewhat resembles Sariel's.
Youkai Flower Midboss
This flower popped out of the ground and attacked Reimu and Marisa earlier in the first stage of Lotus Land Story. It is possibly a flower that has evolved into a Youkai. After being defeated, you can see two red dots in the ground, which are kind of like eyes.
Magic Mirror Midboss (Demon)
This mirror-like being attacked Reimu and Marisa earlier in the third stage of Lotus Land Story. It is possibly an Ungaikyo, a type of Tsukumogami. It might have a relation to the second Magic Mirror Midboss or possibly the same that just transformed, due to this one being a demon-like type and the other an angel-like type.
Nameless Midboss Fairy
This character attacked the heroines twice in Lotus Land Story's fourth stage and again in Mystic Square's third stage. She is noted for being the only nameless character to appear in more than one Touhou game. Her species is thought to be a Fairy.
Magic Mirror Midboss (Angel)
This mirror-like being attacked the heroines in the second stage of Mystic Square. It is possibly an Ungaikyo, a type of Tsukumogami. It might have a relation to the first Magic Mirror Midboss or possibly the same that just transformed, due to this one being an angel-like type and the second a demon-like type.
Nameless Midboss Demon
This character attacked the heroine as she made her way into Pandæmonium during Mystic Square's fifth stage. Since Makai is a world of demons, it is a possibility that she is a demon. Her appearance somewhat resembles Medicine Melancholy's.
Nameless Midboss Card
This character attacked the heroines in Mystic Square's extra stage. It is possibly a tool created by Alice Margatroid to use as a weapon. It is a Jack of an unknown suit.
