what's with the thumbnail??
if this is a glitch from danbooru, it's amazing

Its a gif, except it only changes once. Interesting.

Thumbnail maker got trolled, yo.
Yup, it's a non-looping GIF with one frame normal and the next not.

Aha! Clever...

...I feel like I just got hacked... wow, that was really surprising.

After refreshing it a few time and trying out the save picture option, I can see that it's a gif file with no loop. Man, should have taken me forever if not for you guys.

I heard Out of Touch at the thumbnail lol

Swapping Reisen and Kaguya would probably make more sense.
