I kind of hate how Rokuro is becoming stronger and more kick butt then Benio and how even Mayura is stronger than her. Kamui said that Benio still has her powers so I'm waiting for that, or even a scene of them heading to the Basara that will help restore her power. I'm hoping that Kamui ends up being an corruption (but one that was able to get back his control over himself after a lot years) and I feel like he has a soft spot for Benio, (kinda ship them together but my otp is her and rokuro) and I think he's going to make her stronger than Rokuro or on equal footing. I think after their journey together Kamui is going to develop feelings of comradeship with Benio, and when she thanks him again for helping her become stronger and promises to come back and give him the fight of his life. Kamui with give her two options ten seconds to decide. 1) He comes with her to the front lines on the island and helps her fight the impurities. Or 2) He finds Rokuro and will fight him. And I think she'll just understand that he wants to fight by her (and see her growth himself) and then the manga will flick forward and Rokuro will be at the school where there was a sudden swarm of impurities and the school is being overwhelmed and the two will show up together and save the day via their speed and incredibly fast strength.
Or so I'd like. I don't like how weak they've made Benio. She was chosen to be a twin star exorcist based off of her strength but they make her seem so weak and the underdog. I'm also hoping there will be a few males who take interest in her so that Rokuro gets jealous. But that's just me xD
