Tsumugi Mio

Mio is Shiina's bride thorn.

Diagnosed with a genetic disorder, she seemed destined for an early grave. Being fed on by a Vampdoll, however, is helping her stay alive.

She is the daughter of a noble family that earned their wealth and social status in the steel industry. This has left Mio with connections in the Army brass and various privileges on the one hand, and feeling disgusted with her family's obsession with money and power on the other.

She's reliable, but can be a bit thorny at times.
