For those unaware of the series, Senran Kagura is a hack-and-slash game revolving around several students who are attending classes to become shinobi. The games, however, feature sexual fanservice in the form of jokes and shredded clothing. Shinovi Versus in particular was the first to feature the characters losing their underwear, though it would be censored with bright lights and small pictures of the heads of characters.
Senran Kagura: Shinovi Versus originally launched on the PlayStation Vita in North America on October 14, 2014. It was developed by Tamsoft, and currently has a rating of 67 on Metacritic with mixed reviews. I reviewed my copy earlier this year in the video over at this link, for those wishing to hear my opinion on the game. Currently, the game on PSN remains at $39.99, with no attached DLC.
