Here's a bit of news that's not going to surprise anyone. Shinobi Refle: Senran Kagura has been given a CERO D rating in Japan. CERO D means that the game is only suitable for players 17 and up. Expect there to be sexual content and partial nudity in the game. It seems Shinobi Refle is going to feature exposed underwear, sexual content, and revealing swimsuits/costumes, according to series producer Kenichiro Taka. That makes Shinobi Refle: Senran Kagura the game with the highest age-rating on Switch.
