Narukami

鳴神姫

A bratty, selfish sky god who has an unrequited crush on Tomoe. She steals Nanami's mark and shrinks Tomoe into a toddler, and takes control of the shrine for a short period. She is very demanding and apparently goes through attendants at an unheard-of rate, and seems to take sadistic delight in abusing her familiar. (Source: Wikipedia)
