SIU stands for Slave. In. Utero; it is the pen name of the author of Tower of God. His real name is Lee Jong Hui.
SIU majored in Art Education in college and later undertook South Korea’s mandatory military service. There he met a sun-im (top) that also liked manhwa so he began to draw altogether manhwa. He drew any character arising out of his mind.
According to him the story "was about a guy who entered the Tower chasing a girl that was everything to him and the Tower examined the boy”. Concluding his military service, he had filled up 10 sketchbooks. The argument over those notebooks served him to create 'Tower of God'.
For more than 6 months, he raised his work on his at Naver’s Challenge League until Naver contacted him and asked if he wanted to publish Tower of God officially. That’s how Tower of God debuted and won fame in a short time.
SIU posts regularly descriptions of random characters appearing in Tower of God in his blog and the Naver’s Cafe. The extra content acts as an expansion material for Tower of God, a great story within Talse Uzer.
He regularly blogs biographies about random characters who feature in ToG or have yet to. It's all part of his extensive worldbuilding scenario: Tower of God is merely a part of his grand Talse Uzer Story.
SIU enjoys trolling readers by introducing gender ambiguous characters. Lately, he has even ironically trolled his own characters (Wangnan discovering that Nya Nia is a guy and Yihwa mistaking Viole for a girl) and even created a character like Kim Lurker.
He apparently likes football and names his characters after football players. He also nicknames his characters after fish. Who would've thought of that? And what's up with Ja Wangnan's name? Read backwards, it actually reads (Nan-"I am") (Wangja-"prince"). And SIU's response? "That's some genius wordplay, AMIRITE".
SIU has stated that while he enjoys video games, he doesn't currently play any. He doesn't seem to like being considered old.
Fortunately, he has already finished his 2 year army term. Tower of God was born from sketches he drew in the army, in fact. But he has to go back now and then for a short army practice since he will be reserve army for some time.
Over the course of the series SIU received several assistants such as Sweet Pea, Kate Joh and Void-R who assist him with the drawing and animation for the chapters.
His birthday is on 29th May, 1986.
His favorite fruit is watermelon. He ate three watermelon in two weeks.
