A.N. Sorry it's been so long. Thought I lost this story but finally finished.
-------------------------------
Crystal sat in the library, reading through the book she had selected. After a few minutes of skimming through it, Crystal pulled another book down from the shelf, reading the name.
"Tentacle Demons."
She stared at the cover illustration, a shadowy humanoid figure with a dozen or so writhing tentacles reaching from behind him and wrapping around a naked woman around the abdomen and throat, blood running over the tentacles in both spots. She opened it, beginning to read. According to the book, Tentacles Demons were horrible, monstrous creatures that waited in the shadows for unsuspecting women to pass before catching them and brutally raping them with their tentacles and their actual penises before killing them by ripping them apart. The book said that Tentacle Demons were able to choose whether or not they impregnated a girl. Allowing them to reproduce only if they want to. She leafed through the pages, trying not to stare at the illustrations of Tentacle Demons "feeding" as she scanned. After a few minutes, she set the book aside and returned to the shelf, pulling down a book for each species of her teammates. Once she had the books, she set the one for her own species down, opening it and beginning to read.
"Doing homework?" Angel asked.
"Oh, you're still awake?" Crystal said, turning toward her. "Well, I figured that if I was going to do this job, I might as well know what to expect."
"You shouldn't have to worry about many of those types," Angel said, checking the books Crystal had. "Most of us are actually pretty non-violent species. Mia's kind actually partners with humans for life. Granted, they ensnare the human's mind, but the human is happy and Kitsune feed off of sexual energy at night. It's kind of like being married. Cat Girls usually just make a mess by leaving corpses so we just show them where to put them instead, or what kinds of monsters to give it to, and they generally listen, though sometimes Mia has to...persuade them."
"Wow," Crystal said. "You all really have to...uh..."
"Get around?" Angel smirked. "Yeah. Comes with the job. And the species."
"What about you and Sarah?" Crystal asked.
Angel's smile fell and she sighed.
"I'm not really sure," Angel said. "I really like her. And I want to be able to be faithful, but with the job as it is, that's really hard."
Crystal nodded. "So, what if we find another Slime or Tentacle Demon causing trouble?"
"Tentacle Demons usually stop causing trouble when James shows up, and when they don't, he takes care of it, alone," Angel said. "As for slimes, we've only fought one and that was because the slime was trying to kill one of our old members. I can't remember why, but I don't think I've ever heard of Slimes causing enough trouble for us to have to step in. They usually only hunt once or twice a month."
"You say that like killing two people a month is nothing," Crystal said.
"Not nothing," Angel said. "Human life is precious. But in the grand scheme of things, two people a month is pretty insignificant. It's also not enough for us to track reasonably. And to be perfectly honest, it's not worth the risk. Slimes are incredibly hard to kill."
"I suppose," Crystal nodded.
"Let me put it this way," Angel said. "Suppose we did kill every monster who killed someone, ever. That would be every monster to ever exist. Including all of us. Except you. We'd be wiping out entire species for doing what all living things do. Hunt. Feed. Monsters hunt humans. Humans hunt animals. Animals hunt other animals. It's natural. Most of the time."
Crystal nodded. "So, which ones should I study first?"
"Slimes," Angel said walking to the shelf. "Then I'd go with...this one...then this...then this."
She set a stack of books on the desk. In order, they were Succubi, Arachne, and Sirens.
"Why these?" Crystal asked.
"Arachne are ridiculously common, which sucks because I usually end up being raped by them," Angel grimaced. "Trust me, not a good time. Succubi, as you've seen, are deadly, and unfortunately, they're also pretty common. Sirens are the single most dangerous if we ever go on any missions near the sea or go to the beach."
"We go to the beach?" Crystal blinked. "How?"
"The organization has their own private beach," Angel said. "Mostly safe, but certain water spirits and monsters simply refuse to be caught in traps."
Crystal nodded and opened the first book.
"After those, I'd read Lamia, Echidnae, and Empusa," Angel said.
Crystal nodded and Angel left, allowing Crystal to read.
-------------------------------
I walked up the stairs, groaning and rubbing the bridge of my nose, taking swig after swig of water to try and wash my mouth out.
"You fed?" Angel asked, waiting for me at the top of the stairs.
"Yeah," I said. "Disgusting."
"Blood there's better than feeding our way here," Angel said. "You'll be proud of her. She's been in the library all afternoon."
"Studying?" I guessed.
"Yep," Angel nodded. "I have her reading about Succubi, Arachne, and Sirens first."
"Good," I said. "Go get some sleep."
Angel nodded but leaned forward, kissing me on the cheek before turning and walking away. I sighed, staring at the ground a moment before making my way to the library. When I got there, the door was still open so I was able to slip inside silently. I stood at the door, watching from behind Crystal as she poured over whichever book she was reading at the moment. I could see a stack of books larger than Angel had indicated on the corner of the table and walked over, seeing the Tentacle Demon book on top. I picked it up, Crystal looking up at me as I flipped through the book, stopping at an illustration of five Tentacles Demons. All five were misshapen shadows but each was different. One had a pair of horns curving up from the sides of his head to form a circle and was on the far left, the far right one had spikes on his elbows and three-toed feet as well as glowing red eyes, the one on the left center had a single spike extending upward from his head, and the right center looked human. Behind them was a much, much larger one with glowing red eyes and thick horns sticking straight out to the sides. The largest wasn't showing his tentacles, and the three of the others with spikes or horns each had six showing, but the humanoid one had them sticking out from behind him all the way around. I ran my thumb over the one on the far left and sighed.
