I Have a True Spirit Mansion

Transformation, evolution, true spirit. Reluctant, bewitched, tested, and contracted demon spirit. Running around, working hard without complaining, and willing to be the spiritual master of the wet nurse. A demon spirit that won't give up even if it only has a trace of blood. A spiritual master who braves hardships and dangers for his demon spirit. He is the spiritual master who is also the shit shovel officer. He is a companion, a relative, and a mischievous spirit.
