About her: Wood elves are very discreet. They like to stay amongst themselves. Their exotic beauty attracts the curious and the perverts from the entire world. But not the right kind of perverts... The wrong kind. From time to time though, certain adventurers boast their exploits with such mysterious creatures. It would appear you need a pure heart for them to reveal themselves. Apparently, boasting doesn't prevent pure hearts... Whatever... In any case, Murakawa accepted you as pure enough, or with an intriguing dick, to enter her harem. Have fun with her!
