service, that is usually bound or justified by the narrative. Typical examples There are many elements that may classify a work as ecchi, but these elements have to occur quite often (for example, in all episodes of a show). Graphically speaking, different techniques are used to show sexy pictures, usually by revealing parts of the female body such as the back or breasts. Some of these patterns are recurrent, such as scenes in a shower, hot springs (onsen), or fighting scenes in which clothes are torn apart. The imagination of characters is also a common device for showing their sexual fantasies, as well as transformation scenes of magical girls. In the end, any excuse is valid to show a character partially or completely nude. Nudity Levels of nudity vary strongly between works, depending on the intended audience and the preferences of the authors. For example, in some cases, though the breasts are shown on the screen, nipples and genitals are obscured by props, clothing, or effects. This kind of censorship was typical for Lala Satalin Deviluke in To Love Ru, Blair in Soul Eater and Asuka Langley Soryu from Neon Genesis Evangelion. Meanwhile, in Ladies versus Butlers! and other anime, the nipples are clearly visible through clothing, no matter how thick it is. Nosebleeds are a typical reaction to nudity in Japanese works, as they represent sexual arousal; this is due to an exaggeration of high blood pressure whilst aroused. Panties The use of panty shots (panchira), or visibility of the underwear (panties), is one common motif. Typically, the male will react in an exaggerated manner and be castigated. The color and style of the panties are seen as an indication of the female's character, e.g. white for innocent characters, striped for shy characters, and red for sexually aggressive characters. Panties are a popular main theme in ecchi (for instance, Chobits and Panty & Stocking with Garterbelt), but they are also featured in other shows just for sexual appeal. Sexual activity Although revealing or sexualized clothing, nudity or groping may occur in ecchi works, there usually is no explicit sexual intercourse in the works; in the west, such works are classified as hentai. However, in an ecchi work, it may appear as if a couple are having sex. For instance, the two may be seen in silhouette from outside a tent, appearing to be having sex, although they are doing
