Yurei

Description
Yurei are figures from Japanse folklore akin to Western notions of ghosts. They are thought to be spirits that are kept from a peaceful afterlife. In Rising Sun, Yurei is a Summer monster that is best used as part of a Big Force Daimyo Strategy.

Do Daimyo Upgrades also apply to Yurei?
Yes, they do, and cumulatively if you have several.

During Betray Mandate, can Yurei be replaced by a Monster?
No, it cannot be targeted during a Betray Mandate, as a Daimyo figure cannot be affected by Betrayal.

Since Yurei is a second Daimyo for a player, how do they interact?
You can choose 2 targets from each of your Daimyo Provinces. If your Daimyo are in the same Province, you may only choose a maximum of 2 targets. This means with your Daimyo and your Yurei (counts as a Daimyo) in different Provinces you could potentially kill 4 targets, and gain 12 VP.

What about Path of Sengoku?
Path of Sengoku is a similarly worded ability, to double up the Daimyo bonus with Yurei.
