The tumblr lurking grounds of the Undercity Collective 16+ blog, no NSFW/NSFL, but occasionally posts crude/suggestive humor and alcohol/weed (will tag for both)
So, first thing's first. We are the Undercity Collective! We are a system (and two subsystems) consisting of 36 headmates as of (3/13/26). We're bodily 22, and collectively go by she/any pronouns.
The ones you'll see on here most are:
🍎 | Allen (he/they/heal)
🌸 | Selene (She/her)
👾 | Glitchy (He/she/they)
[We'll explain everyone else later, check back for more!]
Our interests include:
🍎 | Persona, Vocaloid music (particularly Iyowa and Mellowcle), userbox making, psychology
🌸 | Project Sekai, Nikki games, Friday Night Funkin', voice acting, coffee making
👾 | SMG4, Hatsune Miku, memes, coffee
More under the cut!
BYF:
- We are a traumagenic system, but we don't participate in syscourse. However, we believe all systems are valid.
- We will occasionally vent on this blog. It will be properly tagged though, so you can filter it out if you don't want to see it. Take care of yourselves :>
- We are NOT looking for partner systems or partners in general. Helz and I are happily dating, and Selene has an out of system boyfriend.
- A couple of us (Me and Selene) are also fictionkin, so we may post about that sometimes too
- Several of our fictives are not open about who they are a fictive of. Do not push them into revealing it.
- We don't consistently tag fandoms in our reblogs, and our blog is NOT spoiler free, so take care with that
- Selene is Christian and will occasionally reblog Christian content. Please take care if you have religious trauma, and if we reblog something, we'll tag it
DNI:
- under 16 (unless we know you from somewhere else)
-Syscourse of any kind. Frankly, none of us want a piece of that pie, ya know?
-As a matter of fact? Shipcourse too. We're not dealing with that either.
- basic DNI (racists, homophobes and transphobes, pedos, zoos, Zionists)
- Gore / Self harm / pro-ED
- Anti-otherkin/therian
Where to find us:
Simplyplural: OperativeMoonchild (please let us know you're from Tumblr when you add us!)
saw a genuinely mega dumbass take so here's a reminder
if you are a traumagenic system/CDD system that supports endos, I love you, you are so appreciated and needed in this community just as much as endos, please NEVER let anti endos tell you that you arent a valid system or that you're harming system communities by loving your plural and system siblings. You are so important and loved here and you are so needed just as much as every other person. Y'all are so strong for dealing with the bullshit thrown at you so often and i feel nobody recognizes it as much as it should be recognized
a few questions for fictives who are also fictionkin, and whose fictkin source is different from their fictive source! (for example a karkat homestuck fictive who kins noelle deltarune, like a headmate of ours)
is your gender more influenced by the fictive side of your identity or the fictkin side of your identity? or is it influenced by neither/both equally?
is there a side that feels like it is more important to who you are? if so, which one?
do you question if your fictionkin side is actually a new headmate? has that ever turned out to be the case before?
if there's a part of the experience you'd call the most strange/confusing, what is it?
im very curious how this experience varies for other people in other systems
please let me know if this isnt how the blog works i just got here...
This is a question for fictives who also have kin with other fictional media.
Well, I suppose the effects are different per each headmate. For me, the gender of my recent kinfirm feels about the same as my gender from source (some flavor of non-cisgender masc), and my othet kintype's gender doesn't have that much of an effect on my presentation and feelings of gender. For 🌟 though, its does seem to be considerably more affected by kinshifts (oddly enough, falling in line with my gender, because its kintype is my Persona), and for ♟️, they tend to feel more neutral in terms of gender...
For a few days before I kinfirmed my most recent kin, I had actually thought he was here, because we had been hearing his voice (but what I figured out was that wasn't the case). Though most of our Kin or Headmate questioning comes from our host, who is not a fictive but is very much fictionkin (and funnily enough I'm one of the people she had suspected was a kintype at first!) -🍎 (A Takuto Maruki fictive who very recently kinfirmed Flowery Deltarune) with influence from 🃏 and 📺
it's still really funny to me that the system thing works at all. (brain voice) you're so so very upset? i got a plan for this! let's bring out the "not upset" one
see. p5x was brilliant when it made motoha arai. not only is she the first "best friend" teammate in the series who is a girl, but she's also really fucking stupid. she thinks 1.0 GPA means her GPA is number 1. she's futch. she plays baseball. she is the beating heart of the phantom thieves and she would unironically say "chat are we cooked" in real life conversation. instead of talking normally she goes "and then it was like KABLAAAAM KABOOM and he went KRSHHHH KATCHOW" with complete seriousness. she practices imitations on her friends voices. shes still bad at it. when she cooks she forgets to crack eggs properly so she makes what is probably the best omelette you'll eat all week but it is filled with egg shells. her weapon is a spiked ball and chain she uses to throw at shadows. she has a lesbian harem unironically. she gets jealous when other people are lovey dovey to her girl(space)friends. she cant whistle. when wonder talks to her about his visions she unironically goes "oh like in those timeloop manga!" she's died at least twice. she says the word fuck three times within an hour of her becoming a phantom thief. she likes puns and surfing and she thinks if she doesn't go back into baseball her life has no meaning or value because she upholds not only her own dreams but the dreams of the girl who saved her life. she is genuinely just so stupid i love her to death
A lot of us would thrive in a kinder and softer world, but since it’s not, be sure to be the kindness and softness, for others and for yourself, even when the world pushes back. Being gentle with yourself is the first act of real rebellion in a harsh world. Even if no one notices, your own heart and body will thank you.
this post will find you when it needs to find you.
just some facts: you are loved. you are not alone. you are valuable. you are worthy of good things. you are deserving of self love and forgiveness. i’m glad you’re still here.
I don’t know who needs to hear this, but it is okay to grieve dormancy. Dormancy is normal and sometimes healthy, it should be treated as normal and possibly even healthy, and it’s not the same as death, however it is okay to grieve.
It’s like if a friend moved far away, and you don’t know when you’ll see them again. It’s a normal part of life, sometimes it just happens, sometimes it has to happen, but you’ll still feel pain and grief from it, and that’s okay. You experienced a loss. It may not be permanent, but it’s still a loss, and grief is normal.
Please stop trigger tagging with #epilepsy tw/cw/warning/etc.
I need every single person to understand how horrible tumblr’s tagging system is
I go into the tag for epilepsy and its all flashing lights. We can’t use our own tag because people without epilepsy fill it up with improper warnings.
Use ‘flashing’ in place of ‘epilepsy’ in your tags. You aren’t warning people of epileptics, you’re warning us of flashing lights. Please please tag properly. Epileptics say this endlessly and constantly and it’s ignored. You are risking lives by doing this.
Here’s proof of what I mean:
THIS POST IS 100% OKAY TO REBLOG, I ENCOURAGE PEOPLE WITHOUT EPILEPSY TO ESPECIALLY DO SO!
