Miren para los que no saben que es el Ecchi o tienen duda que es el Ecchi les pongo la descripcion aqui:
1.- Segun Wikipedia:
* El ecchi que se desarrolla en situaciones donde se le agrega humor a un determinado momento de índole sexual. Un ejemplo certero sería mostrar una joven en ropa interior o completamente desnuda pero vista desde atrás. Y ella está sorprendida por un personaje masculino al que comienza a sangrarle la nariz. Chobits, por ejemplo.

* El ecchi donde se muestra sexo no muy explícito, es el caso de un super ecchi, también llamado soft hentai. Este género de ecchi es bastante nuevo y ejemplos pueden ser Ikkitousen y Mahou Shojo Neko X.


2.- Segun yo (es que ami se me hace complicado entender la info de wikipedia):
* Es una serie con varios generos (casi no hay series unicamente Ecchi) por ejemplo: accion- Ecchi
* Es una serie que pone a los personajes en situaciones poco comunes con el genero opuesto agregando muchas cosas chistosas o que darian pena ajena.
* La mayoria de este tipo de series tienen historias que son desde comunes hasta cosas imposibles (en pocas palabras existen todo tipo de series para cada gusto)
* Son series que al tener contenido erotico no llegan a ser hentai (sin xxx y si lo tienen es porque algo importante [chistoso o importante para la historia]).

Nota: Si aguien no esta deacuerdo con estas descripiciones avisenme y con todo gusto las quito. Si tienen una mejor descripcion avisenme y la pongo.
