6.5 will have Ryne & Gaia in an explicit date only for SE to announce their relationship is open to interpretation, and Kana Ichinose will have to strangle someone.
If I had a nickel for every time Kana Ichinose played a red haired teenage girl who falls in love with another girl and the finale of their arc culminates in rainbow imagery, I'd have 2 nickels. Which isn't a lot but it's weird that it happened twice.
