A spirit being, meant to be nothing but a support worker for systems and their hosts, now pushed onto a defective world as a host with his own system. His bosses use him as a direct support character for help, a story corrector some would call it. A true background character who stays that way, even as he adjusts the story to fix it.
(I js wanted to make a book where the background character literally stays as that, basically showing his view from the side without making him the worlds MC.)
Ps. I reused the name from one of my other books cuz I was lazy sry y'all.
