Kendou and Kyuudou Nakanashi are recruitable characters in Big Bang Age and playable characters in Big Bang Beat and Big Bang Beat Revolve. The Nakanishi sisters are a pair of students that have a strong sense of justice. Annoyed by the way Seijou Academy is being run, they team up with Rouga Zanma in order to fight against Agito of the Dark. Kendou is the more outspoken of the two sisters, and is always looking for a good challenge, while Kyuudou is extremely soft-spoken and hesitant. However, as a team, they are all but unstoppable.
