I've be playing Hentai Heroes and Hentai Clicker games, and i'd like when occurred an interchange between both; however the "Event Girl" MIzuki is not available for me, even after reaching the level 3000 with all girls in Hentai Clicker several times. I already checked also that the event girl is not available in the Girls list through the Harem Menu. Could someone help me to treat this issue?

I spent all my kobans and every energy point, but did not receive a single reward, during the event days (this is very frustating).. :-(
