Well the manga is quite popular and the last few chapters in the manga are very ecchi. LOL
So I still expect the ecchi level to be the same in season2, but I am expecting the level of the action and animation to be better also.
Also hope they follow it more like in the manga. Since all the girls are complete now in the anime(which they where introduced almost every episode) and unlike the manga it took alot of time before the girls are complete...no let me re-phrase that "BEFORE Tsukune's harem was complete."
