Gilbert in Wonderland (InstanceTopic, 12)
From Compile Worlds
Gilbert in Wonderland is pretty much what it says on the tin; Gilbert Nightray (When he was still 14 or so) goes to Wonderland, instead of Alice herself. Being a mere omake instead of a novel, there are a lot of twists to the story itself. And this being a Pandora Hearts omake, there's a lot of crack to come across.
Synopsis
One day, Alice was reading a book with her sister. However, poor Alice is angry because she's actually a boy named Gilbert, and yet, he is wearing a dress. This refusal to follow the word of a God-ish voice was greatly displeasing, and so, the boy named Gilbert found himself getting kicked into a rabbit hole. From that time on, stuff happened, and eventually, Gil was the king of Wonderland and was unable to wake from his dream.
