Yesterday someone posted the second ED from Mahoromatic to YouTube. This is my favorite of the two endings, although the other one is pretty catchy too.
Warning: This song is an infection. I’m serious. You will need antibiotics to get this tune out of your head.
UPDATE: In the comments below Pixy links to a much nicer, crisper version with helpful subtitles.
Final Fantasy X

A game about the ghost of an underwater football player who travels through time to save the world from a tick that controls kaiju satan. Really.
The Witch Watch

My first REAL published book, about a guy who comes back from the dead due to a misunderstanding.
