Rasetsu no Hana

From Aerandria Scans:

Yakou Hoshino has the ability to create barriers made of water. He then lends his powers to a ‘ghost buster’ company where he meets the agency’s only ‘real exorcist’, a woman named Rasetsu. Though Rasetsu has mysteries of her own including the fact that she’s cursed by an evil spirit, and that she’s the spitting image of Yurara’s guardian ghost.
