SIU

"Author is a genius. Author is a genius. AUTHOR IS A GENIUS." 

- Crazed author preaching the truth

SIU stands for '''Slave. In. Utero'''; it is the pen name of the author of ToG [1].

He regularly blogs facts about random characters who feature in ToG or have yet to. It's all part of his extensive worldbuilding scheme: apparently Tower of God is merely a part of his grand Talze Uzer Story.

And he is a genius.

"Author is a genius. Author is a genius. AUTHOR IS A GENIUS."

He also enjoys trolling readers by introducing gender ambigious 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(holy crap, the genderbending! WHAT WOULD ZAHARD LOOK LIKE?! DEAR LORD! AND THE THOUGHT OF LUSLEC AND KOON EDUAN... WAIITT... DON'T SAY ANYMORE! NOOO!!! )

He also nicknames his characters after fish. Who woulda 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"
