Sisters Royale is a fun fast-paced shooter if you can get past the crazy storyline and somewhat suggestive comments made by the sisters.
It is the first game in 12 years from the team Alfa System, who made Castle of Shikigami III in the Castle of Shikigami series. If you are familiar with the series then from the off Sisters Royal will look and feel familiar, if you compare the two games they look and feel the same. From the vertical scrolling shoot-em-up style and the anime style stills of the characters that tell the story and what a crazy story this one is.
