The center of the mirror world is completely save. However, in order to recollect her past and have her wish granted, Mishiro Usui has to find and shatter 6 different mirrors. Unfortunately these mirrors are scattered throughout 6 deadly realms inhabited by evil spirits and deadly traps. In addition, all these realms excluding the "Realm of Greenery" are sealed. Mishiro has to obtain several keys to open the other realms.
The following realms can be found in the Mirror world:
|Realms||Opened By||Additional mirror|
|Realm of Greenery||No key||Unknown person
|Realm of Beauty||Bronze key||Ryotaro Sengoku|
|Realm of Love||Bronze Key||Ryotaro Sengoku
|Realm of Spirits||Silver Key||None|
|Realm of Blood||Gold Key||Ryotaro Sengoku|
|Realm of Death||Gold Key||Yuzu Hanasaki|
Each realm contains a mirror allocated to Mishiro. In addition, each realm also contains mirrors of other characters.
