Mature (The King of Fighters)

Biography
As one of the Hakkesshu (Orochi's assassins), Mature joins forces with Vice to serve their master, Orochi. The two took orders from one of the Four Heavenly Kings of Orochi, Goenitz, even though they didn't like him. She and Vice were ordered by Goenitz to keep an eye on Rugal, who was attempting to use Orochi's power, so they posed as his secretaries.

When Rugal was killed, Goenitz ordered Vice and Mature to follow Iori Yagami, due to his Yagami heritage of the Orochi power, and bring him to the 1996 tournament. Goenitz was defeated by Kyo Kusanagi and Iori at the end of the tournament, but Vice and Mature betrayed him, deciding Iori was a better ally to help them awaken Orochi. Their plan backfired however, as Iori entered the Riot of the Blood and attacked them, apparently killing them. Although dead, the two can take the form of solid shadows in the living realm.

The two continued to haunt Iori in his dreams and eventually revealed themselves to still exist in the mortal realm before the beginning of The King of Fighters XIII. Both Mature and Vice want to prevent Orochi's power from being stolen by Ash or Those from the Past. Mature looks forward to seeing Iori fight without his flames. They agree not to hold a grudge against Iori and convince Iori to join with the lure of confronting Ash.

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.

Personality
In contrast of 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, she and Vice seem genuinely concerned for Iori's well being and respect his wishes. Their dislike of Goenitz implied that they are uninterested in the affairs of the Hakkeshu and in connection, the Orochi as well.
