This weeks issue of the Famitsu had new information for Musou Stars, mostly regarding the story.
First off, the setting of Musou Stars is brighter than the one of Orochi. The world seem friendlier at least.
The maps are more based on the different series involved in this title instead of a mash-up, like Warriors Orochi.
Furthermore there were pictures showing that Yukimura and Zhao Yun get some rather badass skills. While Yukimura seems to have a fire skill, it looks like Zhao Yun has some wind/ice/water skill.
Now to the story. The synopsis is as follows: A prosperous world is withering because the King who control miracle fountain suddenly died. The Queen told the Princess that they’ll need to summon other world heroes to restore the world. Due to some malfunction, the heroes are summoned at various places in this world.
The throne has 3 heirs, including the princess, which is why the heroes of the other worlds are divided into 3 factions.
Special thanks to BlackKite for the pictures and translations.
