The Mainframe

Yes, but there are some rules you must follow as I made my own license. Below are the terms for using my characters in your projects (such as artwork, stories, games, and other creative works):

• Permission to Use: You are welcome to include my characters in your projects, provided you follow these guidelines.
• Credit Requirement: You must acknowledge me, Sinclair-Speccy, as the creator. Credit should be prominently displayed wherever the characters appear. You may link back to my Mastodon profile here.
• Prohibited Uses: My characters cannot be used in content that promotes hate speech, violence, discrimination, or any other harmful activities.
• Modifications & Derivative Works: You are free to adapt and modify my characters by changing their designs to some extent, altering personalities, or reinterpreting backstories—to create new, original works or personal interpretations (creative liberty). However, you may not:

  - Directly copy or reproduce my character descriptions or other content verbatim or in a substantially similar manner.

  - Make modifications that contradict the Prohibited Uses outlined above.

• Attribution for External References: If you use references from external sources listed on this site, you do not need to credit those sources since I do not own them. However, if you directly use this site as a reference, proper credit must be given.
• Policy Updates: I reserve the right to update these terms at any time. Any changes will be announced on my Mastodon profile or the updates page. Continued use of my characters constitutes acceptance of the revised terms.
• NSFW Content: Most of my characters are adults unless stated otherwise. If you’re unsure about a character’s suitability for NSFW content, please feel free to contact me for clarification.

By using my characters, you agree to follow these guidelines. Failure to comply may result in me contacting you to request removal of the content.

Personally... I think the western side is a mess.

There is a lot I could say about it but I'm trying to keep it blunt. This will be long too so I suggest you make sure you are comfy:

A while ago I was looking for more sources and references on OS-tans so I could work on the personal wiki based on my own research. Amongst the results I got there was this blog called "oresama2chan’s diary". I didn't think much of it until I translated the section that first appeared called "How was the OS daughter born Summary".

Here, I realised the blog shared some of the same thoughts as me in regards to OS-tans, their use and who owns them. However there was one thing that caught my attention on that blog, that being this:

"There are no rules about these types of characters, no general rules for spontaneous net characters, and no rules to protect."

When you think of OS-tans, you probably picture the "main cast" like XP-tan, 95-tan, Me-tan, and 2K-tan. These are the "canon" characters most fans admire. However, after engaging with three OS-tan communities, I found that there are significant issues with how information and research are presented.

OS-tans, or "OS-musume" (a term used within Futaba), are moe personifications of operating systems, primarily Windows. They originated on Futaba's Nijiura board. This board is known for its chaotic yet collaborative nature, allowing images to be freely used, modified, and transformed. This collaborative spirit has led to the evolution of OS-tans.

The Process of Creation:

• Origins: OS-tans started on the Nijiura board, where images and ideas were shared and evolved collaboratively.
• Community Involvement: Artists, craftsmen, and anonymous members all contributed to the creation and development of OS-tans.
• Principle of E&E: "Enjoyable and Exciting" interactions drive the community, leading to the organic growth of characters.

Key Points:

• Collaborative Effort: No single person created OS-tans; it was a collective effort involving many contributors. While you do have creators like Me Aki and NAC (who made XP-tan), this still applies.
• Evolving Characters: OS-tans were shaped and refined by ongoing community input and collaboration.
• Cultural Context: The chaotic nature of the Nijiura board fostered this creative process.

In summary, OS-tans are the result of a community-driven process where many people contributed to their development. The involvement of various artists and craftsmen, combined with the unstructured yet collaborative nature of Nijiura, has shaped these characters into what they are today. Let alone there are no rules such as what counts as an OS-tan and how the term OS-tan should be used...

What I should note though is that the blog states everything may not be correct, but this more of applies to information about copyright so it shouldn't matter.

I am more of a writer than an actual artist. In some fandom spaces, writing without drawings is underappreciated :/

Ehhh... copyright in regards to OS-tans is a touchy subject to me because of my personal views on copyright in general.

The next few lines should be taken with a grain of salt, nor do I condone some things.

You see back in the day you had DejaVu trying to claim ownership of the Futaba OS-tans which led to Me-tan and XP Pro-tan's creators making copyright for their characters respectfully. This mess happened years ago in the 2000s and has since passed on. You also have the Madobe OS-tan copyright from around 2013.

While you should respect the copyright of the creators you still see people out there selling OS-tan stuff on sites like Etsy and RedBubble and making nsfw artworks. This is the case with almost anything else like Touhou and other fandoms. It is sometimes phrased as if these creators will chase after you when that is not the case, at least to me. ME-tan and XP-tan's creators don't seem active anymore and Windows Navi+ isn't around anymore so while the copyright still applies, are they really going to bash you for it?
