The comic is almost 20 years old, and I am still making Anime jokes that not everyone will get. This one is a double whammy too with AT Field (Absolute Terror Field) and Absolute Territory- being 2 different weeb jokes. For anyone curious- and I know there is at least one such person out there, Absolute territory is a joke term for the exposed leg between the bottom of a skirt and the start of the stockings. Absolute Terror Field is from Neon Genesis Evangelion, and funny enough, is the powerful barrier used by the “Angels” trying to destroy the world. So- Celestials use AT-Fields 😛

Explaining the joke, always makes the joke funnier. Try it! You’ll see I’m right! 😀
