Mature

Mature (マチュア, Machua) appears as a member of Iori's Team in The King of Fighters '96. Her official nickname is The Speedy Cruel Beauty (疾走する残酷な美貌, Shissou suru Zangoku na Bibou).

Development
The designers at the time created both Mature and Vice with the image of a "ruthless woman" and a "cruel woman" respectively. Their origin story was mostly based on the notion of Rugal employing secretaries prior to The King of Fighters '96. Both women were unavailable during location testing and were likely finished near the end of the game's production schedule.

Mature's original outfit consists of a long skirt with a slit aside. The director for KOF XII notes that the costume played a role in highlighting her "legs" which is her charm point along with emphasizing the unique movement of her fighting style. However, in KOF XII, the costume was changed to a pants suit close to the secretary theme. The director was aware that people might be disappointed in the costume as it concealed Mature's legs, but he points out that the quality of the 2D dot graphics allows them to add more detail to the wrinkles and fabric's of her clothing whenever she executes an attack.

Orochi Saga
One of the Hakkesshu, Mature joins forces with Vice to serve her master, Orochi. She often takes orders from Leopold Goenitz, although she doesn't like him. She and Vice were ordered to keep an eye on Rugal Bernstein, who was trying to use Orochi's power. They posed as his secretaries. When Rugal died, Goenitz ordered Vice and Mature to keep an eye on Iori Yagami and bring him to the 1996 tournament. They didn't win the tournament, but when Kyo Kusanagi and Iori defeated Goenitz, Iori entered the Riot of the Blood and killed Vice and Mature. Although dead, both women continue to haunt Iori as shadows to entertain themselves.

Tales of Ash
Not knowing why they still exist, she and Vice tempt Iori to enter the newest tournament and volunteer to be his teammates once more. The women want to prevent Orochi's power from being stolen by Ash or Those from the Past. She looks forward to seeing him fight without his flames. After the climax of the KOF XIII tournament, Iori's magatama returns to his possession and the weakened Orochi seal begins to strengthen itself once more. Both she and Vice ask if he truly wants to accept the magatama and the Orochi blood once more, offering him a final chance to completely eradicate the cursed fate from his bloodline. When Iori refuses their offer, the women fade once more out of existence. They state they will meet him again in his dreams.

XIV Arc
Mature and Vice return once more while Iori visits a grave. Vice tosses him an invitation to KOF, she mentions that this KOF is just the beginning of the nightmare. Just like in the previous tournament, Mature looks forward to seeing Iori fight with his flames. After the climax of the tournament, Mature and Vice don't stop Iori who was going to seal Orochi. She states that all destinies are beginning to shift, with Vice agreeing, she comments that Iori can't resist his blood once it boils. The women return to the dead once more.

Personality
In contrast to Vice, Mature is ruthless but she likes to toy with her victim a little bit, often using her charms. She seemed to have liked Rugal while they were together. Though Iori killed both of them and continued to be hostile to them as phantoms, she and Vice seem genuinely concerned for Iori's well being and respect his wishes, despite clearly being an enemy of theirs. Their dislike of Goenitz implied that they are uninterested in the affairs of the Hakkeshu and in connection, the Orochi as well.

Mature is bisexual.
