9banta is a manga artist and web designer based in Japan. She has been drawing since she was three years old and always had a knack for offbeat designs - drawing people with limbs sprouting from their heads and demons. She is known for drawing animals and shirtless male characters, and enjoys fussing over outfits and accessories. In 2018, she became obsessed with One Punch Man and started drawing fan art of the series daily. In 2020, she participated in a Twitter hashtag prompt called “#CharacterDesignMashupGame,” where she came up with the character design for a demon foreman based on nine prompts. Her creative partner, Hiroki Kamishiro, wrote a short story based on the character and setting he came up with, which became Zigoku’s Foreman, a comedy-fantasy manga set in a construction site in Hell. The world-building in Zigoku’s Foreman is inspired by Buddhism and kabuki, which are both topics she enjoys researching.
