スピたん Spirits Expedition―in the Phantasmagoria―

There’s a mountainous crag to the northeast of the Continent of Dragons called Dragon's Claw Marks. No one in the recorded history has been able to cross that area safely. However, they did not have a newly invented airship!

You play as the aspiring and newly appointed captain of this vessel, Loty Eiblyss, but you didn’t exactly come with your own crew of hardened sailors. In fact it’s more like a rowdy well-to-do family of women posing as a crew, coupled with an actual lady sword master (your teacher) and an another mysterious girl. At least this family of nine women appears to be trained to fight when the need arises.

[Edited from a forum post quoting White Masq]

The crew Loty Eiblyss leads is made of the sub-spirits from the Rakios Spirit Corps that Yuuto led in Eien no Aselia.
