That's from Ishibumi's newest work.

The MC is Slash Dog and took place in DxD Universe with characters from DxD appearing in it, i.e. Azazel, 13 year old Vali, etc.

Basically, it's DxD with Tobio Ikuse as the MC but is made in a more serious way.

~That latest work (working title not yet released) is a FREE WEB novel.
