History
Yui is a mage who lives in the dream world, with dream being her thema. She was sealed because being asleep was part of her thema research. Her power is in the cardinal class (next after the headmaster) and without her restraints her magic has the dangerous potential of causing the entire world to fall asleep.

Meeting Arata
Arata met her when she saved him from being killed by Akio to stop the breakdown phenomenon. She pulled him into the dream world at the last moment. There she introduced herself, and explained to him what archives and themas were.

Because Arata met with her, the power of the magic king affected her. Causing the entire school to go to sleep.
