Akiko Natsume

Akiko Natsume is the CEO of Japan's largest military contractor and Ryunosuke's fiercely protective mother. Her chief goals are to reclaim her son from her husband and capture Nuku Nuku so the android can be reverse-engineered.

Because she avoids pursuing Ryunosuke through legal channels, Akiko relies on repeated abduction attempts by Arisa and Kyouko. Her methods are ruthless and manipulative, but her concern for Ryunosuke is genuine.
