Mayoke no Seijo wa Munou de Yakutatazu wo Yameru Koto ni Shimashita

Angelina, the Saint of Warding, is one of a number of saints in the kingdom, yet while all the other saints are revered and loved, no one in this perfectly peaceful country seems to value her powers of “warding off evil,” calling her useless and a creepy witch due to her black hair. When her fiancé breaks off their engagement to be with the famous Saint of Healing instead, Angelina decides she's finally had enough. Why should she protect a kingdom that hates her? So she packs her things and sets out on a journey to find new meaning and maybe even love.
