Lumen Celeritas

"A weird human who makes such bizarre sounds...There's no doubt about it, you must be the culprit!"

- Lumen confronting Yabusame in Earthen Miraculous Sword

Lumen Celeritas (ケレリタス・ルーメン Sereritasu Rumen) is a lazy youkai who claims that she was a hero long ago. If she absorbs moonlight, she becomes very destructive.

Personality
Lumen has a hopelessly calm disposition. During the daytime she dozes in the sunlight, and at night she sleeps beneath a tree. She talks and acts very childishly, but anyways it's because she's always sleeping defenselessly in the middle of the road. When she absorbs moonlight, she goes berserk and starts saying random words and throwing rays of light everywhere.

Abilities
Lumen can absorb sunlight with the shell on her back. She can also absorb moonlight, but that makes her go berserk.
 * Take and bundle light

Background Information
Because Lumen is a sunlight-youkai, she's usually only active during the day. She's famed as one of the "Three Lights", and resolved a certain incident a long ago. However, if she ends up absorbing moonlight she becomes very violent and destructive, but she doesn't realize it, not even the fact that she has destroyed villages with her power.

Name
Her given name Lumen is Latin for light. Her family name Celeritas is the Latin word for speed or swiftness, which is often explained to be the origin of the notation c, the universal notation for the speed of light in a vacuum, as popularized in Albert Einstein's famous equation E = mc².

Design
Lumen has short, boyish grey hair and her eyes are the same colour. Her hair is decorated with talismans on each side of her head. She has a red shell on her back, which she uses to absorb the light. In her crazy mode (EX-Lumen), her shell and the talismans on her head are broken. She wears a sleeveless white haori and a short black skirt.

Lumen's Appearances
As a sunlight-youkai, the cloudy incident is problematic for Lumen, so she goes searching for the culprit, but runs against the enemies instead, believing them to be the culprits, who defeat her.
 * Earthen Miraculous Sword

Frustrated and hungry after being defeated, she goes to sleep, but by now the heroines have defeated the real culprit and the sky is clear again. A sleeping Lumen ends up absorbing moonlight, and her violent and destructive persona emerges, attacking the heroines again for little reason.

Additional Information

 * She is the first character that has a more powerful form for the Extra Stage, seconded by Sese Kitsugai.
