- The reason why the eighteenth release is named Sengoku Retsuden is that there are some characters whose names are based on the Sengoku period people, or the Samurai Warriors characters:
- Masamune derives from Masamune Date.
- Nobunaga, or N.Naga, derives from Nobunaga Oda.
- Ayame's genre, Lovely Kunoichi Pop, derives from one of the Sanada Ten Braves.
