My circle (student club) at a Japanese university is preparing for the school festival. One option for participating is to draw and submit a 「ジャンルくじイラスト」. Does this translate to "genre lottery illustration"?
What does that mean? Does it mean that each submitted illustration is not guaranteed to be featured in the festival booth, but that the illustrations used in the festival will be selected out of all of the submitted illustrations by random? Or does it mean that the genres to choose from for drawing the illustration were determined by lottery? Or...?
Here is the full paragraph: 「ジャンルくじイラスト募集要項 ジャンルが書かれたくじを引いてそれに書かれたジャンルのイラストを書く、ジャンルくじイラスト企画を今年も行います。くじを引く人は例会、その他の場所で学祭担当が対応します。参加は各自の自由。」
The rules also state,「デリケートなジャンルに関しては各自自重する（ディズニーとか）」.
What is デリケートなジャンル, and what is 各自自重する?
I Googled デリケートなジャンル but could not determine a basic definition that seemed to apply to the various webpages that came up. What constitutes a genre as "delicate"? I tried looking up 各自自重する in online dictionaries but I could not find an English translation. Is this saying that if you want to draw Disney characters you need to make them original in some way? Is it possibly saying that fanart is not allowed?
Thank you very much!
