Random #touhou theory

Okuu (Utsusho), and Kanako’s reactor in general, are probably thermonuclear and not just nuclear:

-

If in would be radioactive, Touhou heroines would be dead just from that. Thermonuclear projects that were in works irl are not radioactive, but meant to contain plasma 10 times hotter than the sun to be actually effective. Touhou doesn’t need that hot of a thing and magnetic force to contain since this reactor is half powered on Yatagarasu divine spirit contained within Okuu

Underground sun is what Okuu and her place are often called, and thermonuclear reactions are the ones that happen in the sun

No proper thermonuclear plant was established irl, and projects are kinda forgotten by public right now. Gensoko is just the right place for not implemented and kinda obscure or forgotten technology to exist
