Ecchi but no nudity/ sex is there, however in the anime, you can see the female protagonist's underpants while using her "Panty-scissors" on the male protagonist. Also there are many scenes in which she has to stand nude in front of her boyfriend but the body parts are covered with lightening/dark.

No violence.

No use of profanity.

No Use of alchohol/ smoking / Drugs are shown in the anime

Well there are some scenes that can leave you woundering " What the HELL is happening!!" But if you surpass them u'll see its cuteness.
