Kiruko Matsuoka

Kiruko Matsuoka, also know as the Queen of the bad jokes, is a character introduced in Volume 4 of Highschool DxD: Яe-birth, and serving as a secondary antagonist/protagonist of the next one. Dubbed 'The strongest Human ', Kiruko is an idol-hunter which admires the class idol Shiori Kamiyama, and see in Ichijou Tsukino a possible love rival. She's also the current host of the Evil Black dragon King Vritra, as well as all the Sacred Gears containing the fragments his soul.

She's the classmate of both Shiori and Ichijou, but because of her affiliation with the Black Team, she rarely appears during classes, missing the first bimester because of it.

Appearance
Kiruko is a average-heighted, thin and short young woman with indigo bleached hair, unfocused hazel eyes and fair skin. Because of her usual stalker nature, she has extremely deep blacks around her own eyes, and sometimes her skin color can become paler, not to mention the experiments done on her while in the Miyama house makes her cover herself in bandages to hide her cirurgical wounds and scars.

She's usually seem wearing a dirty, ripped version of Kuoh's uniform with white shirt with black linings, magenta skirt and maching corset-cape. She wear various others clothes when on break.

Personality
"That was not a joke. Jokes are funny. What you made was a spoken genocide weapon!"

- Ichijou Tsukino Kiruko is considered one of the most bizarre characters in the series, even more nonsensical than her fellow members of the Miyama house or even the cast in general. When first introduced, Kiruko was intimidating, cynical, threatning and low-toned, trying her hard to intimidate the current Red Dragon Emperor so that he stayed away from Shiori Kamiyama out of jelousy. When she saw it wouldn't work, Kiruko downright threatened to kill him instead, only stopping because of the school's bells announcing another period.

The next time they met, however, Kiruko showed her true colors: She has an extremely short memory span, doesn't like remembering things that don't concern her, is pretty vague and unfocused in anything else, and likes to make horrible jokes for the sake of it. She shows no resentment for ichijou and his crush for Shiori, nor his position as the Sekiryuutei, and clings on him like a sloth for no especific reason, much for his annoyance. Despite this, however, she can be friendly, supportive and even poetic if such things ever crosses her mind, but only in such occasions, since her own mentality is random and unfocused as the rest of her behavior. She has a rather friendly relationship with her Dragon Vritra, as it serves as her tutor and friend, despite the clashing personality of both. She's also somehow dim-witted and close-minded, as she reached Balance Breaker on all of her sacred Gears, individually and even able to use Vritra Promotion, but doesn't even try to reach the full potential of them.

History
Just like any other girl from the Miyama house, Kiruko was a nameless abandoned child picked by Enma Miyama is his rage against the heavens. Learn how to use language, the powers of Meta Concepts and becoming a Light Eater, she would soon leave the Miyama house like the rest of the children, but for her own random reasons. Later, after being adopted by another family, she discovered her Sacred Gears, and because of her status as a Light Eater, she soon developed Balance Breaker for all of them, discovering Vritra sealed in them right after it.

She enrolled in Kuoh academy after a complicated dice game, and ended up in class 1-B, together with Ichijou tsukino and Shiori Kamiyama, that would be later her secret crush.
