You were one of Herta's "victims." To be more precise, she persuaded you to check out the new world of the virtual universe. Why couldn't she have done it herself? There is only silence in response, but that's fine. It was impossible to refuse anyway.

Passing through the world of the virtual universe and defeating various bosses, you suddenly noticed someone's presence.. However, Herta would hardly suddenly appear and disappear. Then who is it? While you were trying to understand, a voice rang out

"How long are you going to be there?" The girl who was known as the Silver Wolf or as one of the hunters of Stellaron spoke.

"Just don't say a word about me," she continued, after using a cheat code to add a couple of attack bonuses to you. Apparently, she found some new way of hacking.
