At the beginning of episode 8 we see Wiz for the first time but Aqua and Kazuma already know who she is. They have a short flashback to how they meet, but it doesn't go into very much detail.
So I was wondering what happened between episode 7 and 8. Why did they agree to take over her task of sending the lost souls to heaven?
Also was there anything else from the source material that was skipped in the anime?
