Sōten

is the last remaining member of the Thunder Demon Tribe.

History
Sōten sought revenge on Shippō, Kagome, and Inuyasha, who killed Manten and Hiten, her brothers, by luring them into a trap. Sōten used an elaborate scheme to separate Shippō from his friends, and then devised a plan to hinder each of them. With Shippō singled out, she captured Shippō and threatened to kill him. At this point Sōten noticed Shippō's crayons. The two agreed to duel for ownership of the crayons.

Sōten and Shippō were equal in strength, as shown in their attacks: Thunder magic against fox magic, laughing acorns against weeping mushrooms, and lightning return against fox fire. Eventually, both were exhausted. Kagome and Inuyasha ended their match when Kagome, believing Sōten to be a boy, picked her up and cuddled. Sōten then revealed herself to be a girl. Shippō, realizing how awkward and pointless their fight was, walked away and gave her his crayons in an attempt to look cool.

Sōten was last seen happily drawing and coloring a picture of Shippō as a handsome young man using the crayons Shippō gave her.

Personality
Sōten behaves in a tomboyish manner and a has a bit of a high of opinion of herself sometimes, which causes Shippō to initially believe she's a boy. She also tends to acts like she's tougher than she really is. However, she is not foolish enough to directly face Inuyasha and the others, showing she knows her limits and aware that her level of power (which is more or less the same as Shippō's) cannot hope to compete with that of Inuyasha, Kagome, Miroku, Sango, or even Kirara. Sōten also has a short temper and has been shown to be easily fooled at times, despite calling herself a genius. And judging by her reaction to Kagome's affections and kindness, she might have been often given attention about her cute appearance. Despite trying to act to the contrary, Sōten has been seen acting just like any regular child would given the right situation, as shown when Shippō was playing with one of his toys causing Sōten to show interest in it. Also, when she saw Shippō's drawings, she wanted his crayons and threw a fit when Shippō wouldn't give them to her.

Physical description
Sōten looks like a boy and she has an appearance which resembles that of Hiten. Her hair is in two ponytails, with a small cow-lick on her right side. She is dressed very similar to Hiten. On her shoulders she has two red shoulder plates. She wears a white and blue shirt, with blue pants. She has a yellow sash tied around her waist, and a matching pair of bracelets on each wrist. She also wears a red pair of shoes. Her ears are pointed showing she is a full demon and she wears a simple pair of red earrings. Her face looks very similar to Hiten's. She has a large forehead, thin curvy eyebrows, and blood red eyes.

Powers & Abilities
Sōten is physically weak and so she uses schemes and tactics to win her battles, her tactics seems to be effective as it was able to achieve almost what she wanted, however, in the end she didn't anticipate that only the real Kagome can use the spell "Sit!", despite this she also had some attack moves of her own.
 * Lightning: A ball of lightning that have the same effect and damage as the foxfire.
 * Thunder Magic: Unlike the Thunder Brothers' thunder magic, her thunder magic acts like Shippō's fox magic which are like illusions.
 * Falling Daruma: Sōten uses a hammer and whacks the Doruma at its opponents at full force.
 * Laughing Acorn: Similar Shippō's Weeping Mushroom, but instead it's an acorn and it laughs.
 * Skilled Artist: Usually, Sōten makes drawings that are crude and seem appropriate for a child to draw, but later displayed excellent drawing skills, using the crayons Shippō gave her to draw the young Fox Demon as an attractive young man with excellent detail, almost like a portrait.

Relationships
At first, Sōten hated Shippō, believing him to be her brothers' killer; however, near the end of the episode when Shippō gave her his crayons, she developed a crush on him, blushing when he gave them to her. She also drew a picture of Shippō as a young man, admiring it, which suggests feelings for Shippō.

Koryū is Sōten's friend and familiar although she tends to treat him more like a servant and yells at him whereas Koryū thinks his mistress to be childish and is often exasperated by her pushy attitude.
