Lee Siwoo was an ordinary job seeker with one rather embarrassing wish.

He wanted to become a petite, beautiful girl.

After sleep-talking that wish one night, he wakes up as Lee Siun, with a completely different body and access to something even stranger: the Spearcraft Gallery, an interdimensional forum filled with master spearwomen.

Siun knows nothing about spearcraft, so she does what any sensible newbie would do.

She follows the tutorials.

Unfortunately, the techniques posted by the forum's experts are far beyond anything she realizes. What seems like simple practice to Siun produces astonishing results in the Tower of Trials, and before long, everyone around her assumes she's a once-in-history spear prodigy.

The masters of the gallery aren't any better.

To them, their mysterious new member isn't a clueless beginner.

She's a monster pretending to be one.
