A Super Mario Thing/WMG

Demo's master is in fact, Raocow himself
Look at the way he talks, and the fact it was Raocow who came up with the whole vegetable thing.
 * Thanks.
 * Wasn't Demo's master referred to as a female at some points?

Demo is from Gensokyo.
Before fighting Rumia, she claims that there's something familiar behind the boss door.
 * She's the lovechild of Kogasa and, uhm... Homestar Runner?
