Stranded Otherworld Princess

The Stranded Otherworld Princess (漂着した異界の姫) is a boss character that appears when the player spends too many turns on a map.

Appearance
In boss form she has the appearance of a girl with long purple hair and wearing bondage gear riding on the backs of 4 masked humanoids chained together. Two 4 speaker boxes are carried by her mount, one on each side.

When she has been defeated and joins your army, she no longer has a mount and instead carries a microphone stand.

As both an enemy and a unit under your control, she apparently attacks using sonic waves/sound.

Description
世界の挟間に彷徨える古き人類. 死神となりすべての生物を襲う.

From an ancient race of humans, wandering between the worlds. Having become a death god, it attacks all living things.

Tactics
With a base level of 40 and high damage plus holy armor she is quite a formidable enemy. With Holy armor she is weak against Darkness attacks, so characters equipped with a Dark Magic Book can do high damage to her. Oktavia's Magic Barrier passive skill also has a chance to cut damage received from this boss by half.
