Looking for a ecchi manga

[HannanGinan]

The things i remember of the manga was the protagonist who was a boy who had a gun or cannon between his legs and I do not remember if it was an angel or a magic girl who had to use that weapon to fight demons.

So the girl needed to use MC "leg cannon" to fight monsters. Lewd!
I've never seen it but i'm interested.

I am sure You means this one.

The image used in mangahere is much more "communicative"
