@dfjhgdi (Pro tip: don't bash on the keyboard when you get frustrated that all the good usernames are taken. That's a joke, mind you. Don't get upset.) ...Allow me to explain...according to Taku's previous Patchy works...she was dabbling in...well, an alchemy of sorts. It was like a cross between necromancy and alchemy. She used parts from various things...(which all ate her and she somehow got out...Gensoukyo logic.) one of which was C*** from D***** B***...you know, that one guy.) and she somehow ended up becoming addicted to it...and made a...thing...that would consume her and once it was done, release her. ...So, yeah, she kinda acquired a new fetish. And...well, that's what happened. ...I don't know how to explain shit any further.
...And, in closing, a quote from Touhou creator ZUN himself.
...when asked about the definition of the word "maid", ZUN said this: "A maid is a mythical being we've all heard of, but none of us have ever seen one." ...Best quote ever. Gets you thinking.
