The Harp Yumi (琵琶の和弓 Biwa no wakyū, lit. Biwa Wakyū) is a Yumi that is introduced in Fire Emblem Fates. Despite its Japanese name suggesting that it is modelled after the Japanese lute, the Harp Yumi bears no semblance to the instrument. The Harp Yumi is viable for combat nevertheless, owing to its low but usable Might and the fact that it is able to increase the Resistance of all allies located within two spaces post-battle.
Analogous to the Harp Yumi is the Violin Bow, which is also associated with a musical instrument, has poor might, and invokes a skill boost to nearby allies. As the Harp Yumi cannot be found in the story or found in castle events of Conquest, or obtained as a gift from My Castle battles, it appears only in Birthright and Revelations.
After attacking, grants Res +4 to allies within two spaces for one turn.
This weapon's Japanese name is named and based off of a Biwa, a Japanese lute-like instrument that evolved from the Chinese Pipa.
