First of all, this girl name is 結月恭子 = Kyoko Yuzuki. R18 goes with this translation as-well. I saw other site misspelling this girl name pretty badly. If someone has another opinion about this translation i would like to hear it.
EYAN-090 is Yuzuki second release. She is very pretty but i don’t fully understand yet why is she suddenly so popular. In any case EYAN series is doing very good stuff lately.
