Hi! I've started Luciana's 3-Dazer. When coming out of the HQ, I saw that Eva Saint is available to fight. But grogor's walkthrough doesn't mention her at all, and neither does luthius's 3-Dazer specific walkthrough. So I tried to defeat her but she's too powerful for me right now (Nash takes HUGE damages!). So my question is, will she stay there permanently or do I have to defeat her within a specific time frame?
