TheYuzuSystem

Hi! We’re the Yuzu system!

[theyuzusystem]

Intro!

Hello! We are the Yuzu system!

Here’s a quick intro to our system:

-Members (Updated as of Jan 29 2026)-

Sun: ☀️, He/Him. He’s a fictive of Sun from fnaf. Very cheerful and generally enthusiastic! He likes learning new skills and dislikes mean people. @suns-blog-fnaf

Moon: 🌙, He/Him, He’s a fictive of Moon from fnaf. Somewhat distant and a little rude, but he seems to get along well with others when he tries. He likes naps and dislikes fronting. @moons-blog-fnaf

Mercury/Dave/William: ⭐️, He/Him, the one writing this right now! I’m the host and a fictionkin of William from fnaf and Dave from dsaf. I’m also a common vampire bat therian. You can find my kin and fandom stuff at @thedavefictionkin . I like tiramisu and dislike bigots.

V1: ‘V1’, He/Him. He shapeshifts. Not much info on him but he’s chill. @v1s-blog

-Origins-

We aren’t really sure of our origins, but we think Sun and Moon are either neurogenic or traumagenic. V1 is willogenic.

That’s all, feel free to ask questions!

[theyuzusystem]

Oh hey another V1

Hey.

[theyuzusystem]

Hmmm, none of us are good at questions..

If you guys have jobs (or roles) in your system, what are they? -Mr. Puzzles

What are the best source memories for any of you guys? -Moon

I’m a trauma holder, Moon and Sun are caregivers, and V1… is V1

I vaguely remember that Moonie and I would hang out with the Dj a lot!!

I’ll never shut up about Jack cutting my hair.

I don’t have source memories.

[theyuzusystem]

S E N D A S K S!

Please, we’re so bored! You can ask any or all of us almost anything!

Yep!! I’d especially appreciate asks!!

I am bored as well…

I’m also here, and I promise you I’m interesting.

(For those who don’t know, the yellow text is Sun, the blue is Moon, the red is V1, and the purple is me- William/Dave/Mercury.)

[theyuzusystem]

The V1 Situation

Has calmed down, and he’s kind of adjusted to being part of the system. And, as his partner since like, the other day, I can confirm he’s only somewhat distracting now.

We’re off to go take turns posting now!!

Indeed.

Bro Dave needs to stop being sappy, it’s killing me. He is a HOPELESS romantic.

Also, again, SEND ASKS! We love asks!

[theyuzusystem]

Hrmmm…

Chat if I make Sun and Moon and V1 do school for me am I in the wrong? I really don’t feel like being in charge today.

Personally, I don’t mind!

I was going to nap…

Damnit I don’t want to work.

[theyuzusystem]

Inner system dating.

Hi, so me and V1 are now officially dating, but we don’t know the first thing about inner system relationships. Can anyone give us some advice/info??

We’d appreciate it.

I’m so happy for those two!!

Yes, Sun and I are here too. We would also like advice on how to support this duo.

[thedavefictionkin]

Hello!

I have made a discord for age regressors, syskids, permaregressors, etc!

Check out the Davey’s Daycare! community on Discord - hang out with 1 other members and enjoy free voice and text chat.

The discord is open to all! The only rules are no discrimination and NO NSFW!!

You can still join if you post nsfw stuff, just keep it OUT of the server!!

[theyuzusystem]

:)

[theyuzusystem]

please, stop posting

lmao no.

Nah.

NO CAN DO!!

Cope harder.

[theyuzusystem]

We’ve all posted!

The fighting is over!

@thedavefictionkin , @suns-blog-fnaf , @moons-blog-fnaf , and @v1s-blog have all posted!!

Anyways, send asks, we’re still bored!!

[theyuzusystem]

I love when..

I open tumblr and now that we all have blogs we’re all fighting to post so we’re rapidly switching.

We’re fighting with cartoon smoke and everything.

I should post first actually.

No, me!

And who invited V1??

Anyways yeah it’s silly.

[theyuzusystem]

We have updated our intro!!

[theyuzusystem]

Umm guys.

V1 turned into Miku earlier.

It was super cool!!!

Was it though?

…Anyways, if he doesn’t fade by February then I’m introducing him to the blog, adding him to our intro post, etc. Or if someone wants to meet him before then jus let us know.

ALSO SEND US ASKS PLEASE!! We’re still bored.

(We’re trying to post more on this account, bear with us.)

[theyuzusystem]

Shapeshifting Alter??

V1 was formed as a Jack Kennedy fictive, but just last night he sort of changed… into Steven. I don’t know why or how this happened, but I know it was still V1, just with a different form and voice.

We were shocked to see him transform in the headspace! He quickly changed back though!!

I wasn’t surprised.

Does this mean V1 is fading away like we feared, or something else??

[theyuzusystem]

hello !!!! Heard y'all wanted asks , so here! Hellooo - mellifluous-sys

YAYYY

YAYYYY

Hello. :}

(V1 says hi too!)

[theyuzusystem]

S E N D A S K S

Please!! We’re super bored! Also, should we make an agere blog too for when I (Dave/Mercury/William) age regress or feel like talking about regressing?

You can ask us almost anything!!

I’m here too.

(We’re trying something new. The purple text is Dave/Mercury/William, the yellow text is Sun, and the blue is Moon.)

[theyuzusystem]

Hrmmm…

Debating whether I should introduce V1 to you guys. I’m afraid he might disappear any day now still. He doesn’t seem as solid as Sun and Moon.

hrmmmm….
