User:Night Shift - Rumia

Rumia (ルーミア) is a youkai with the ability of manipulating the darkness, and is one of the few youkai that doesn't seem to belong to any particular species.

Rumia has the ability of manipulating darkness. By covering herself in pure darkness, she is able to prevent sunlight from passing through the darkness, as it is magical in nature and can render traditional lights such as torches useless within it. Because of this, people who happen to go inside the darkness would not able to see anything, but it looks like even Rumia also cannot see, as she might crash into trees while flying. The appearance of the darkness outside its region looks like a spherical circle that is moving. Rumia says "I'm fine in moonlight" meaning she doesn't need such ability on the night of a new moon. Should also be noted that while her field of vision is reduced by her own ability, she is used to it enough to be able to read Aya's newspaper even with almost no light, while Aya herself couldn't write notes nor reading her notebook. At that time, she has also shown that her light-blocking ability doesn't work only as "on" (complete lack of light) or "off", but she can control how much light can pass through the darkness, as she let only a bit of it entering to be able to read the newspaper. Additionally, judging from one of her spellcards, she seems to be able to turn into some sort of dark mist. The names of her spell cards are also related to night and darkness (Moon Sign, Night Sign, Darkness Sign). Rumia's design shows that she has red eyes and short blond hair. She wears a black vest and skirt, and white blouse with a red tie bordered by two large red beads around her neck. She also has small red amulet tied to the left side of her hair, making it look like a ribbon. However, she can neither touch nor remove the amulet.

When interviewed by Aya prior to the events of Embodiment of Scarlet Devil, Rumia complained that other youkai were coming into her darkness because the article Aya had written suggested they could also avoid the light and heat like her. She also complained when Aya requested there be enough light for her to take notes, as it seems that Rumia's eyes are very sensitive to even a little bit of light; most likely because she's so used to the darkness, even considering nighttime to be bright. Aya was a bit disappointed that Rumia has no goals in life.

Rumia appears again to participate in a test of guts being held at the Hakurei Shrine, along with Sakuya Izayoi, Youmu Konpaku, Yuyuko Saigyouji,Wriggle Nightbug, Mystia Lorelei, and Cirno. At that time, she is first seen talking with Mystia and Wriggle, and then within her sphere of darkness while chasing Youmu. She also reappears later in a similar crowd when the Three Fairies of Light preparing a festival at the Hakurei Shrine. Rumia however did not seem like she was part of the preparation and wasn't visible during the festival itself.
 * EX Rumia: It's broadly rumored among fans that the amulet-ribbon is some kind of "seal", and that taking it off will release her true power. In some doujinshi, when the amulet-ribbon is removed Rumia develops an EX form in which she looks more mature, has wings, and/or wields a giant dark sword (usually a Stormbringer).
 * Sonanoka~:Her catchphrase in fan works is Sōnanokā (そーなのかー) which is a pretty childish way of saying "Is that so~." Rumia first says this in Embodiment of Scarlet Devil during Reimu's scenario. This is reflective of the childish and ditzy personality she's given in most fanart.
 * Team ⑨: In fan works, she is often seen with other lower level, childish characters like Cirno, Mystia Lorelei and Wriggle Nightbug and Daiyousei.
 * "Team ⑨" is a term used in the Western fandom. In the Japanese community, they (Cirno, Mystia, Rumia, Wriggle) are referred as the "Bakartet" (バカルテットbakarutetto, "baka" + "quartet").
 * The 7th day of the month is known as "Rumia's day" among the fanbase, and various artists are more likely to draw many fanarts involving her. That's because in japanese this day is also called "nanoka".
 * Similarly to Yuyuko Saigyouji and Yoshika Miyako, she is often portrayed as a glutton that is extremely fond of meat (most notably humans and Mystia Lorelei). The three of them are sometimes seen together and are known as the "hungry trio" in the western fanbase.
