Doujinshi with three stories: 1) First one depicts what frustration fueled aggressive boredom burnt in creative manner would result in: it's a comiket market commentary told through slightly reimagined scenes from original visual novel. Continued at the end of the book. 2) Titular story: Tohsaka's out of jewels, so she sets out for a tropical island rumored to hide legendary gem. 3) Illyasviel takes full advantage of Einzbern magic, in a way you never knew you wanted to see.
