Is this a hentai adaptation of the part in the light novel where Stella and Ikki had sex? Despite the average artwork, its still pretty hot.

I never knew how badly I wanted and/or needed something like this. I hope this gets translated ASAP. I still can't believe our boy Ikki went through ALL TEN CONDOMS in one night. That means not only is his 'sword' is more powerful than his magic, but Stella may just be nothing short of insatiable. I'll bet that somewhere in the back of her mind she REALLY wanted Ikki to go in raw, but rationality prevented her from doing so (she was the one who supplied the condoms after all).
