Maiden of the Needle, Vol. 2 (manga)

Yui’s blessweaving has the power to alter the entire kingdom’s fate. A whirlwind of changes is in store for Yui; not only is she now engaged to the former king, Argit Lomestometlo, but her new fiancé tells her she must become the head of House Nuir to avoid being ensnared by her family’s pact! First, though, Yui needs to earn the current king’s approval, which she can only do by proving that her skills are second to none. The perfect opportunity to show off her blessweaving arises at the royal ball, where an important noble is wronged at the hands of a certain Nuir.
