Just saying. The series is not very ecchi based. It's not even tagged ecchi on nearly all of the manga info/reading sites. There is some ecchi references, but they are not as evident as in series like History Strongest Disciple Kenichi. Just to note, series like Fairy Tail and Magi may also contain slight ecchi references. For example, Lucy taking a shower and Aladdin groping people. I understand that Nanatsu may be a little bit more obvious in the scenes, but it is not a theme or focus of the manga. Hence, it's not really "ecchi". It's more of a manga which contain some ecchi elements.
