Mato Seihei no Slave (Demon slave) Roleplay Infos!
Hello and welcome!
Before we get down to business, let me tell you something: Thank you for the time you’re taking to read this!
It will take you a few minutes at most, but the effort of going through all I have to say means a lot and I believe thanking you is the least I could do for your time :)
I’m sorry for the format of the prompt, Reddit makes it weird :(
Also! One more thing: I know what you’re about to read might sound pretentious, but please keep in mind that it isn’t my intention! I try to be the friendliest dude possible once we get in touch and any formality in my speech is probably due to English not being my native language. I know I’m asking a lot and my tone may sound iffy, but be aware that I really appreciate any feedback you might have whether you’re interested or not!
So, let’s get down to business!
As the title suggests, I’m looking for someone interested in GMing a long term roleplay set in Demon Slave! Let’s talk about the person before the game though!
I’m a graduating student from college and while I currently have quite the free time in my hands, I am not going to be online 24/7. Don’t get me wrong, I’ll dedicate this roleplay a lot of time and effort since I LOVE roleplaying. However, I have Irl stuff to focus on so I ask you to have patience and I’ll do the same :)
I won’t ghost, disappear or leave you hanging for days without warning, but patience would be reaaally appreciated!
As for my style, I exclusively play on discord and write in third person! I’m an amateur writer so the length of my replies is quite long —reaching and surpassing the 2k characters limit if I have enough to work with— and I do appreciate longer replies!
I love OOC and consider it the real core of a functional and fun roleplay, especially in this one considering how the powers work. I won’t ever cross any boundaries we set, this is something I want you to know and don’t worry about, but this is a long term roleplay and… I’d love if we could become friends :) no need to share name, location, or any irl details. I would just love to find someone who has similar interests, talking about dumb stuff and have some lighthearted conversations together!
Okay, enough about me! If you have questions —about me or the roleplay itself— you’re always welcome to ask, but let’s move on for now!
So, who am I looking for exactly? In a few words, someone who can write a lot and is interested in creating an interesting yet lewd story! I’ll help you, I won’t leech off your back and suck your goodwill dry, but I’d be looking to play only one character: a male, straight OC I can create on your tastes :)
Anyway, let’s delve into the details of the roleplay!
Demon Slave… this is where I usually make a brief talk about the OG material, but what else can I say besides that this manga defeated my in terms of lewd? I’ve managed to read 90-something chapters before dropping it because of IRL issues, but now that it has become an anime with two seasons I wanted to pick it up again in the form of a roleplay!
My knowledge is really rusty and likely outdated since I checked and there are 80 more chapters… however, the main core of the whole thing is to come up with a scenario that contains both lewd and smut (as much if not more) and story!
Specifically, I’m looking to play a someone who can replace Yuki. The hows and whys can be discussed in chat, but we don’t have to stick necessarily to everything that happened in canon! Actually, I’d love if we could go haywire! Like, I don’t want to set a roleplay where every girl is fawning over my dude and wants to have sex 24/7 with nothing else in mind, but when it comes to monsters, enemies, powers and such I’m more than happy to explore aaany ideas that you might have!
Aaalso, if you would be willing, I really love power fantasies and I’d really appreciate if we could include some way for the mc to be stronger :) I know the whole concept is “earning” the power through Kyouka, buuut… if you have anything in mind and would be willing to discuss this, I’d really appreciate it!
If what I said so far caught your interest and you’re considering sending a message, remember writing the word “Cookie” in your first message! It will let me know you’ve at least read this part! If you want to let me know you’ve read everything… just be yourself :) write about yourself, tell me what you liked about the post, which picture you liked the most, reply to what I wrote and it will be enough!
Okay, time to talk about the last few things: Smut-Story ratio and development of the game!
This is an ERP so smut will have quite the important in the upcoming story, especially in this one. However, if I had to choose between story and smut I’d always pick story! Don’t get me wrong, there are multiple characters that I’m looking forward to do some baby-making training with, but I believe that a story whose only focus is sex would get boring real quick.
So, the story would be the main focus with fights and smut being a fantastic side dish :)
As for the game itself, I like mechanics. I like rolls and dice and all that D&D-esque approach, but I also really love story-driven roleplay where we sort out the events through roleplay and ooc. As long as there’s clear communication between us, I believe we can make it work without any dice, stats, and what not! Though fights are kinda mandatory… remember, every fight scene leads to a lewd one so there’s that!
I’ll share my kinks and limits in chat, this message is really long as is already, but ALL characters must be +18 and here’s a quick summary of those I’d love to include:
Kinks —> Ecchi scenes, bareback, breeding, French kissing, yuri/lesbian/F4F scenes, romance, drama, buildup, dark themes such as non con and Harem.
Limits (exclusively related to sex scenes and to my character, in story I accept everything) —> bathroom stuff (scat, piss, farts), nipple & genitals piercing, torture, gore, bimbos, mindless smut/romance (as in “F character randomly falls in love with MC and wants to suck his dick dry!” I can accept it once for a yandere or something similar, but not everyone.), hypnosis and M4M
One last thing: I’ve said this already but I have a life outside this rp. I will dedicate a lot of effort to make something we will both enjoy, but if I start to feel like I’m the only one putting in effort, I’ll reserve the right to close the roleplay. It happened too many times that people joined, let me do most of the job and limited to the roleplay without any ooc, worldbuilding and anything else. I have time for one roleplay and I’ll dedicate my mind and soul to it if we click together, but if the effort isn’t mutual I won’t waste time. Sorry if this sounds harsh :(
And that’s it!!
I hope to hear from you soon!!!
Bye!!
