Shimada Takashi (嶋田 隆司)
Story Writer
Hometown: Nishiyodogawa-ku, Osaka
Birthdate: October 28, 1960
Recognizable feature: droopy eyes
Shimada went by the name Takashi Kaneyama until 1984 and is a graduate of Hatushiba High School in Higashi, Sakai. He's the more public-facing half of the partnership—he frequently shows up solo at movie premieres, events, and interviews, which has earned him the joking nickname "The Non-Working Half of Yude" among fans. He's mentioned being a mischievous kid who loved reading and drawing manga; his favorite TV drama was Playgirl. Before teaming up with Nakai, he'd already spend time sketching Kinnikuman on notebook paper just for fun.

Nakai graduated from the same high school and used the name Yoshinori Iwamoto before 1984. He's the quieter of the pair and prefers to keep to himself. He was a serious baseball fan and player as a kid, dreaming of going pro, but didn't really get into manga until he met Shimada. His favorite actress is Mariko Kawana.
