looking through own legs
Bending down and looking at the viewer through one's own legs. Frequently seen when a character is standing up, with their head and torso fully bent forward so they are looking behind them upside-down. There are other possible poses, such as Danbooru post #3323448, Danbooru post #2860988, and Danbooru post #3320641.
This is mutually exclusive from view between legs since that tag refers to the viewer's perspective. This tag refers to the character's perspective. Both instances may be seen together though, such as Danbooru post #3155529.
