Part 1 of the NSFW side story is up!

Not linking directly to the smut, but you can find it on the Side Stories page on sunspot dot gay. For a little extra security, the page is password protected (shouldn't need an account). The password is:

Around 4000 words. Part 2/2 should be about the same. Happy reading!

Arc 4 Progress Update (good news!)

TLDR: Discount code to read 4.01-03 early; Arc 4 begins Nov 16, maybe 23; smutty side story this week.

Hi readers of Sunspot! It's the start of November, which means I've overshot my predicted "mid-October" timeline for when arc 4 would start releasing. Thanks for your patience; I've been really busy! Good busy, but busy a...

4.03 Patreon Release

One could say that my venture into the umbilical abyss of the hallway to reach my synthetic body was a reflection of the Flame-woven bridge across that solipsistic void my mind had crossed yesterday…but that would be over-dramatic. What I actually did was go over to the hallway and find the light switch.

Once the shadows were banished, i...

4.02 Patreon Release

CONTENT WARNINGS: Objectification, human trafficking, implied rape (in backstory, not on-screen)

--------------

“Amane?” Alice called.

I heard the scuffling of a chair moving in the other room and turned to see Amethyst, almost three meters of gemstone mecha, looming in the doorway of her gamer cave. She waved at me. I wave...

4.01 Patreon Release

Hi public readers! 4.01 to 4.03 will release for patrons before 4.01 goes public, so if you want your fix of Sunspot a few weeks early, it's only $5!

The public NSFW side story is still coming! It might go up this week or next.

After euphoria came shame.

My first time in the doll had been eye-opening, a singular exp...

3.12 Patreon Release

Yuuka took me to the rooftop.

It was a cold, clear afternoon in Tokyo, the kind I’d become somewhat used to by now, those pale-blue winter days that made the cityscape feel as though it were simultaneously looming straight over me as well as impossibly far away, floating somewhere in the sky, an endless vertical assemblage of glass and s...

3.11 Patreon Release

“Thank you for saving my life.”

Takagiri’s expression of gratitude was difficult to face directly. She bowed to a perfect ninety-degree angle, arms against her sides, black ponytail hanging over her shoulder, delivering the words with crisp clarity as though she’d been rehearsing them for days, which perhaps she had while in her ex...

Poster Comm Series #5: Yuuka

The fifth and last of the main Radiances in this series! Main version, eyepatch, and alt with her eye at full power.

Don't worry, we'll also be doing Ebi and Ezzen. Maybe Takagiri too. Also maybe redoing Hina's since I feel we can do better on it with more experience now. In other words, I'll be continuing to give Mjeow a lot of business.<...

Info on Delays, Yootie Life Update, Second Story

[TLDR: I'm moving! Expect some more delayed chapters for the rest of August, and afterward, I'll be starting a second story.]

Hi readers! Sunspot has had a lot of delayed chapters recently, and I wanted to shed some light about what's causing it and what it means for the story, since I'll be too busy for the next couple of...

3.11 Delayed One Day, Yuuka Poster WIP

Hi patrons! I'm super busy, so 3.11 won't be coming out for you guys until tomorrow. To tide you all over for those grueling 24 hours, I've elected to share the nearly-complete WIP of Yuuka's entry in the poster series. All hail the Yuubs.

3.10 Patreon Release

None of the prosthesis prototypes were ideal. That wasn’t really the fault of the students who had made them; it was legitimately hard to come up with useful features to cram into the space of the front half of a person’s foot, and they’d put a truly admirable amount of effort into coming up with novel solutions and a wide range of feature...

Radiance Tier Perma-sale

Hi patrons & readers! Thanks for supporting Sunspot! This post is to notify you that I'm dropping the price of Radiance tier (the main advance chapters tier) back down from $10 to $5.

Why: Back in May, I raised the price of Radiance tier from $5 to $10 (only for members who signed up after that, of whom there are about 30), in accordan...

Arc 3 Cover Raw Art

You might have noticed that Arc 3 now has a proper cover everywhere you can read the story! I figured I'd post the full, title-less art here with a little director's commentary; I'm still working on a gallery page for patrons where all the art I commission for the story can be available to download. For now, here'll do.

This lovely piece w...

[Repost] Side Story + Info

Hi folks! I haven't used Patreon for this kind of outreach before, but hopefully this will reach a bunch of readers who aren't in the Discord to see announcements there.

To the point: Did you know that the old side story I wrote back in December 2024 is available for everyb...

3.09 Patreon Release

(Sorry this is late! I think it came out strong, though)

---

Ai’s students had been divided into six teams for the purposes of working on my prosthetic. Each team was a mix of undergraduate and graduate students, four to seven people, and had come up with their own prototype. She arrayed the prototypes before me on an open space of...

3.08 Patreon Release

The nature of the Todai “cuddle puddle,” as Hina affectionately referred to it later, was that most of its participants would leave in stages throughout the early morning, so I didn’t wake up in as much of a tangle of limbs as I had been expecting.

Alice, workaholic that she was, got up bright and early at 6:30 AM; her phone alarm pu...

3.07 Patreon Release

“An actual fucking ghost. Made of his Flame.” My head was buzzing with adrenaline from the last two minutes as I stared at the point in space where Sugawara had disappeared.

“Sure looks like it,” Ebi agreed. “Right back from the dead, a Flame facsimile of who they used to be. Who’d’ve thunk?”

“And he—and he went t...

Poster Comm Series #4: Amane

Another poster by Mjeow! Her mech is not normally anywhere near this big but she's taken some liberties for the photoshoot.

Part of an in-progress series of seven: Hina, Alice, Ai, Amane, Yuuka, Ebi, & Ezzen.

3.06 Patreon Release

Content warnings: Possession/spiritual violation

---

I’d repeatedly heard Sugawara referred to as “comatose.” This was true, but what everybody had left out was that he was also mangled. His body was a patchwork of burn scars, and there was no hair left on his head. His nose was destroyed. He was surrounded by bee...

3.05 Patreon Release

Unlike what I’d seen of Ai’s premier magitech—Amane’s bionics and Ebi’s chassis—the coffin was not a pretty thing: a mess of plywood, sheet metal, 3D-printed parts, and exposed wiring. It did resemble a coffin in shape and size, large enough only for a user to lay down inside it, but more like the skeleton of one, affording no privac...

3.04 Patreon Release

Ai initially seemed confused that everybody was yelling. She opened her mouth, said a few syllables in Japanese, saw me, hesitated, then switched to English.

“I just didn’t want to leave her alone.”

“So you brought her here?” Yuuka almost yelled. She jabbed a finger at Amane. “Red ripple, Ai, fuck!”

My ha...

3.03 Patreon Release

Making a mantle was a lot more involved than the instinctive immediacy of blood magic. I needed a full infomantic scan of my body, custom substrates, a lot of integration testing, and likely days’ worth of weaving for the final implementation once every other step was completed. I certainly wasn’t getting it done today, and I doubted I would...

3.02 Patreon Release

[CW: unreality]

------

If one were told that there was something in the corner by someone running on a life-threateningly severe sleep deficit, most rational people would find it easy to dismiss. But Takagiri was a flamebearer, and things are often weird for us, especially when it comes to what we see. The eyes are the windo...

Poster Comm Series #3: Ai

Another poster by Mjeow! Her necklace is a carbide cutting insert; not actual jewelry she wears, just a prop for the photoshoot. And how about those sweat patches in the alt?

Part of an in-progress series of seven: Hina, Alice, Ai, Amane, Yuuka, Ebi, & Ezzen.

3.01 Patreon Release

The next day, Alice finally found the time to sit me down and debrief the events of the Barbecue Inferno. It was a pale day; the clear and cloudless February sky held nothing to occlude the sunlight as it washed the Tokyo skyline into harsh, neutral off-whites, spilling through the east-facing window of the penthouse’s meeting room and onto th...

Poster Comm Series #2: Alice

A goodie for patrons to tide you over during the hiatus!

Part of an in-progress series of seven: Hina, Alice, Ai, Amane, Yuuka, Ebi, & Ezzen.

Poster Comm Series #1: Hina

A goodie for patrons to celebrate the end of Arc 2.

Part of an in-progress series of seven: Hina, Alice, Ai, Amane, Yuuka, Ebi, & Ezzen.

Blog Thing: Character DNA

In the Arc 1 Author’s Note, we talked about inspirations for Sunspot as a whole. This time, I’d like to instead talk about where individual characters come from, because it’s fun and I think a little peek behind the curtain is a nice reward for all of you who support me financially. This is going to be kind of rambly, as I’m just listing...

Arc 2 Retrospective

We made it!

Hello, readers! Welcome to another end-of-arc author’s note slash blog post slash postmortem slash peek behind the curtain. This is the early release of the public one; for you Patreon supporters, there'll also be an exclusive "Character DNA" writeup following this.

This time around, I want to talk a little about writ...
