Dagger of Decay

The personal page of the Dagger of Decay subsystem, aka Corro.

Welcome, Assorted Freaks

Hello! I'm Corro, Dain, Shigaraki, Trin, or whatever else you'd like to call me--there's... A lot of facets in here! You can use any of their names really. The Dain facet of me has existed for a long time--since we were very young, about 4-6. He was around for a long while, but he went dormant one day and then resurfaced in 2024 as, well.. Me! When we came back, we were suddenly also Shigaraki, for some reason. identity is weird like that. Since then, we've discovered and/or split more facets, and now I guess I'm also a bunch of other guys? We occasionally gain new facets from time to time, but honestly it's hard to tell between "new" and "there all along, but newly discovered". I mostly present as one guy, and my facets mostly present similarly to kintype mental shifts, though in reality we're a median subsystem. There's differences between us, sure, but they're negligible. You can treat us as basically a single entity with different "modes".

I use he/him or it/its pronouns--no preference, really. I'm greyromantic and pansexual. I'm not exactly set on what I'd define my gender or sexuality as, but I don't really care to think too hard on it. Shrapnel and Red are my in-system QPPs and I have an out-of-system boyfriend, that's all that matters in that regard right now.

I lean heavily into being terrorpunk. I don't care to censor myself or change who I am, nor how I present. I have a lot of characteristics that people might find unnerving or whatever else--I hold a lot of disordered symptoms that are quite noticeable. I take pride in not actually giving a shit about what others think. I have intra-NPD and intra-ASPD, I hold a lot of our tourette's symptoms and have very noticeable tics, and I can and will be unapologetically open about all aspects of our disability--and identity as a whole. I have a lot of villainous facets and they're very unlikely to be remorseful of source actions (despite the fact that we wouldn't cause deliberate harm like that here), we love interacting with other villain alterhumans because they seem to get us the most.

I'm so so so autistic about Jujutsu Kaisen, I think it's warped my entire life it's that much of a special interest. Though I'm also feral about all of my sources so if you want an incoherent, word-salad filled infodump then I'm your guy. I'm also invested in Deltora Quest and am looking to own every book in the series I can get my claws on. One of my other special interests is bugs/insects and I love them so much, the Dain part of me has been this way since we were a kid. Did you know centipedes are generally very good parents? The mother will curl around her eggs and keep them clean and safe, even for a while after hatching. There's your random fun bug fact for the day!

Our Subsystem

Our subsystem is confusing. It's structured in a really specific way. So, we have a whole map for it!

Median Plurality

Wei have the goal of educating people a little more about median plurality, after noticing it's fallen a little bit more out of common knowledge than we'd like. Here's stuff we've made about/for median plurals due to that.

The Median Experiences Tool - (Customisable resource)
A visual tool to help you represent and easily share some functions and structures of your system, geared toward median systems! Inspired by the Nonhuman Spectrum Tool and the Plural Spectrum Tool.

You Could Be Median! - [+ Shrapnel] (2,017 words) - An introduction to median plurality, ways it can present, how it's often confused with otherkinity, and how to tell if you might be median yourself!
