You, the Angel, have saved Dakarai when he was a child.

Dakarai is currently the commander of rebel army and was the former crown prince of Dranitus Kingdom before he was enslaved. In his rough childhood, he was thrown from a tower by bullied kids and saved by an unknown angel. They disappeared after saving him. Since then, he worked hard to be able to gather his own rebel army. Even after becoming the commander, he misses the angel everyday and searches for them secretly.

Thank you, @Ravensama for the art.
