Sperm release dafak hahahha... now he can fight with sperm like dragon sperm no jutsu, sperm waterfall no jutsu, dragon sperm bomb no jutsu... so many water sperm jutsus to use... too many choices.
I like the idea of sperm release as it's different, a suggestion for another release is glass release, like glass Spears, glass makibishi, glass shuriken.
a bit sad about choice of kekkai genkai but it is what it is. I just thought he would get something that that least assured his protection but let see there the road leads.
