エドランゼ ～Come on!水戸姫様～

Shogun Tokugawa Masamune starts reforms, but it also gives way to criminals of all sorts, and Edo gets drowned in crime. A hunt for criminals with huge prize is announced while Shogun goes to hot springs. Mito princess is left in Edo, so she is a tempting target for all sorts of warring parties snooping around.
