18+ ( ADULT CONTENT) Ecchi-Pantsu:- The visibility of the underwear ( panties) is one common motif. It often leads to strange reactions between a female and the male protagonist, who would accidentally (or not) look at the underwear. The reaction can be quite varied, depending on the color and style of pantsu, but usually the male is punished for looking, regardless of the reason. The color and style of the pantsu is not chosen at random. Both are seen as an indication for the female's character. Innocent females wear simple white or kawaii themed underwear (with hearts or similar motifs), shy girls prefer theshimapan (striped panties); in some cultures red is seen as 'of the devil' or "naughty," etc. The pantsu theme itself is so popular, that it is an important object in anime like Chobitsor Sora no Otoshimono. Coincidently, both anime's fourth episodes are based on the pantsu theme as a narrative element alone. The anime Panty & Stocking with Garterbeltgoes another step further, in which pantsu is used as a weapon. But even if the pantsu is not the main topic itself, it is often shown due to a "careful choice" of camera angles. In this case, it can be rightfully called fan service, since it is not needed for the story itself.
