Somebody knows who are the artists from the animations on the video?

I saw this video compilation on Tnaflix and Spankbang and tried to find these artist by myself. Unfortunetly without success because the character in the video has the name Nagato_(Kancolle) trying to search on rule34video.com i din't find anything related to the animations on the video and mostly Nagatoro_(Ijiranaide, Nagatoro-San)
animations because they names look aliket with only a tiny difference. Tried to search on Rule34.xxx and there is a bunch of art of Nagato_(kancollle) but no animation related to the video compilation. I truly would be grateful if someone could helpe me in this challenge.
