Pachinko Development Story

Wandering around the KYORAKU company web site I came across a recruitment section including two manga that tell (dramatised) stories of the development of machines. The image above is from one of the manga that tells the story of the development of a pachinko Winter Sonata, a popular Korean soap. Pachinko machines like this are developed to attract more women into pachinko parlours as audience numbers are declining. I was struck that the team, at least as shown in the comic, has no women designers, which raises the question of whether there are any women designers?
