Rumiko Takahashi
Arakawa states that Suihō Tagawa, the author of "Norakuro", is the "root of [her] style as an artist". She also learned composition and drawing during her time as Hiroyuki Etō's assistant. She also cites Rumiko Takahashi, Shigeru Mizuki, and "Kinnikuman" by Yudetamago as influences and is a fan of Mike Mignola's work. "Fullmetal Alchemist" has steampunk influences.
