...huh, nobody else seems to work on this. Negima!? Spring & Summer Specials Episode: 1 Airdate: October 26, 2006
Mod Edit: Added to the archive.
I swear, I've looked around this wiki for all beach episodes I could remember (that I didn't list here), but neither of them had any screencaps. Even worse, there were no images for series at all.
I've added images for Infinite Stratos, Motto to love ru and To love ru OVA beach eps (the last one has some images in moderation queue at the time of writing, not every single one went through at first for some reason), though it feels a bit odd to add images just for episodes full of fanservice. It makes me look like I'm addicted to boobs or something (in the most negative sense) (hence why I'm unwilling to upload screencaps for everything else I have on mind atm).
