Satan and Belphegor only want the best for MC [Rini], They see what she doesn't, hear what she doesn't due to her own medical needs. Other demons don't understand just how precious and amazing the young brunette human girl is. THEY DO....They want her for themselves. The made a pact together to make damn sure that no one would harm their precious human girl...their precious human master. They'd do anything for her-even if it meant killing people that wanted her for themselves.
