Sui Hutami is a Japanese manga artist and writer known for creating fantasy and magic-themed series, several of which have been adapted into anime. Hutami is the original creator behind the manga series Dungeon People, which received an anime television adaptation in 2024. For this series, Hutami is credited as the original creator and character designer.

Prior to Dungeon People, Hutami created the series Mahou Shoujo Nante Mouiidesukara, which was adapted into an anime in 2016. Other notable manga series by Hutami include Sekai Maou. Hutami also authored the manga series Yotsukoto. The creator has been active in the Japanese doujinshi (self-published) market, participating in events such as Comitia under the circle name "Sagarisakamichi" and producing works including the RPG no Naka series.

Hutami's published manga bibliography includes work beginning around 2015. The creator's body of work reflects a consistent focus on fantasy settings and magical themes, with a tendency to explore the operational or administrative sides of fantastical environments. This distinctive approach is central to Dungeon People, which follows a thief who begins working as an assistant to the magical administrator of a dungeon, learning to manage monsters, set traps, and maintain the labyrinth rather than simply exploring it.
