If Hibari ever gets her revival in the future, make sure you get her buttlover. She is probably the best samurai to date and some players say she is the physical attack version of Anya. 2x ATK and DEF when skill activates, cheaper than Anya (23 cost vs. 35 cost), and her AW passive lets her become a token, so you don't have to worry about her dying affecting your star count.
