A Certain Scientific Railgun
I figured if anywhere would appreciate this, it'd be the fediverse. ToaruOS is a hobby operating system which has been completely coded from scratch as one developer's 12+ year long educational project. It not only features the made-from-scratch Misaka kernel, but also the Kuroko coding language. It can even run on real hardware. You might recognize ToaruOS from [jdh's Tetris OS video](https://youtu.be/FaILnmUYS_U), where it was used as a reference source.
