Can anyone identify this anime?

[Iris3]

I remember seeing a clip of anime about a month ago.
The drawing was similar style to keijo.
In the clip, a dude shot some sniper looking gun, and the bullet like went just between this girl's boobs.
I think it was some kind of school/military setting too. They were wearing uniforms.
I also remember reading a comment about how the maker of the anime mainly produces hentai, so this anime is very ero.

Can anyone identify this anime from my lousy memory?
Thanks

I think it's Highschool of the dead.

It looks similar so I'm gonna give it a try. Thanks!

I thought all day about it. There is also the possibility that it is also Triage.
