realisissa

I want to make sure I cover the correct sense of "realisissa." Could you clarify:

- What language or field is this term from (philosophy, literature, linguistics, a brand name, etc.)?

- Is it a real-world concept, a proper noun (e.g., a work, organization, or person), or a fictional/constructed idea?

- Do you want an encyclopedia-style article about an actual concept, or a neutral, fictional article describing a created concept?

If you’d like, I can proceed with either option. Note that I can also draft a concise, neutral wiki-style entry for a fictional concept named "Realisissa," clearly labeled as fictional, in under 300 words. Please specify which direction you prefer.
