Mei Xing explains to Morgan that she and Yakumo are monster busters and that they're after the thing killing all the women on campus. Morgan reacts accordingly:

Mei Xing expected that and tells her to fuck off for all she cares. Morgan is still suspicious though, revealing that all of the victims did have one thing in common: they were all named Maria. They had nicknames, shortenings or used different parts of their full names but they definitely had the name Maria in their name somewhere. So Morgan plans to gather all the Marias in one spot to draw the killer out. Pai shows up, having figured out the connection herself, and offers to help.

Yakumo says that there are five more Marias in university which is complicating his plans for dealing with Spazug. He calls Steve for help who asks Youko for help who tells him that the monster killing the women might be a water demon like her. Basically, it uses its mist to accelerate the water molecules in their bodies to dry them out and leave them in ashes. But it has a weak point: since mist is just water spread out into the air, if it needs to attack, it has to materialize its body first. So the way to deal with it is through heat. Oh, and Yakumo is to continue to not let Mei Xing in on the Devil King being alive and Huang being dead.

Meanwhile, Mei Xing asks Pai why she's looking for Maria in the first place. Pai says that Maria is the descendant of Madurai but Mei Xing presses for details which gets awkward because Pai can't tell her that she's looking for Madurai to deal with Benares and they need to deal with Benares to deal with the Devil King who's still alive which Mei Xing isn't allowed to know about...then Mei Xing calls out to her roommate Maria (ach!) and asks if she have five or six people over tonight. No explanation! Maybe it's an orgy? Who cares? It's on! Maria gets a call from her house and Mei Xing jumps Yakumo for some reason but I'm pretty sure neither of those things are important.

So Yakumo and Mei Xing go around gathering Marias with various bribes, having to deal with clashing personalities as they get them all in the same room together. Naturally, none of the ones there have anything to do with Madurai so Yakumo wants to focus on fighting the Mist Monster...only for Mei Xing to reveal her roommate Maria is missing.
