Some sexual yaoi manga drawings drawn by mio, only done for laughs, for example a suggest blowjob (hand on the head) but nothing explicit shown at all.

Some sexual innuendo, very suttle and infrequent, although in a lot of episodes.

Sakurai finds a porno magazine/dvd and looks through it and finds it "very amazing" it is not shown, only the cover that shows a woman in a bikini

Note: there is no fan-service in this show, it just has some sexual references rarely.

Only comedical violence, some gun shots and explosions, one of the characters has a crush on sasahara and when she gets angry/stressed she usually fires a firearm, but its only played for laughs, none of the characters get hurt or are in pain.

There is some blood in some episodes, nothing gory.

Lots of slapstick violence.

Some people die in some episodes, although it's always done for laughs and it's nothing explicit.

"Oh My God", "damn It", "idiot", "stupid"...

Depending the subs and dubs, the words "bitch" and "shit" are used in some episodes. Although very infrequently.

Nothing explicit whatsoever.

There is some smoking and drinking.

there is a scene of a man smoking a cigarette, it is not on the screen for too long.

Some mild action.

Some dark humor.

The show is not frightening whatsoever, it is very lighthearted, funny and random.
