My favorite light-novel: slayers fanart.

There is a mini-theater in the postscript of the book.
L-sama(Lord of nightmare),kanzaka(Author),subordinate-S(Demon King of the North / Lei Magnus-Shabranigdu ) are the characters.
We can see their outlook on author's new year greeting card, or Lei Magnus sometimes appears on anime or in SNES game(araizumi's design).

In the new slayers book "SLAYERS READING",kanzaka explains　:
In Kōma War ,Lei Magnus was fighting against MAZOKU as human,but his lover was killed by human,and his Ruby eye awoke by despair.
And in the same book kanzaka says : Lord of nightmare (sea of caos) doesn't have a decided appearance or a decided personality.　
In postscript theater, She takes personality of Lei Magnus's lover.

WHATS !?
