I'm not a mathematician, but we are getting asymptotically closer to actual hentai every time the author draws an ecchi scene. What a master of their craft. It's beautiful how evocative this artist makes their work without ever actually crossing the line into actual sex. I'm literally clapping. Nukenai Seiken-chan may not be classy, but it is art, insofar as it's the work, arguably the magnum opus, of a master of "HOW DO THEY KEEP DOING IT?".
