Before the first season of The World God Only Knows anime adaptation was aired, two promotional videos were created with completely unique animation.

PV1

The untitled PV1 was originally available to download on the (now-defunct) official TWGOK website, kaminomi.jp (archive link). This is why all the available re-uploads of it are in 240p, as that was the only quality you could download it in. I’m uncertain, but it was probably shown at Comiket 2010 as well.

PV2 “Kiss, Kiss, Kiss…”

“Kiss, Kiss, Kiss…” was included on the special anime promotional DVD bundled with the Limited Edition of Manga Volume 10.
