Their dislike of Goenitz implied that they are uninterested in the affairs of the Hakkeshu and in connection, the Orochi as well. 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. She seemed to have liked Rugal while they were together. In contrast to Vice, Mature is ruthless but she likes to toy with her victim a little bit, often using her charms. She states that all destinies are beginning to shift, with Vice agreeing, she comments that Iori can't resist his blood once it boils.

Mature and Vice return to the after life.ДЄfter 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. The women want to prevent Orochi's power from being stolen by Ash or Those from the Past. Not knowing why they still exist, she and Vice tempt Iori to enter the newest tournament and volunteer to be his teammates once more. Although dead, both women continue to haunt Iori as shadows to entertain themselves. 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. When Rugal died, Goenitz ordered Vice and Mature to keep an eye on Iori Yagami and bring him to the 1996 tournament.

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. However, in KOF XII, the costume was changed to a pants suit close to the secretary theme. 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. Mature's original outfit consists of a long skirt with a slit aside. Both women were unavailable during location testing and were likely finished near the end of the game's production schedule. Their origin story was mostly based on the notion of Rugal employing secretaries prior to The King of Fighters '96. The designers at the time created both Mature and Vice with the image of a 'ruthless woman' and a 'cruel woman' respectively.
