Is amazing how tight and well-written this series is, Neko Taoru has proven herself to be one of the best yuri writers and artists in the business. The pacing is just perfect not too slow but not too fast either and every single character has been given a great depth no matter how big or small their role is in the plot.
I think this chapter has further cemented Lapis and Natori as the end pairing while Diana hopefully gets together with someone else (ideally another girl but Gran has proved himself a nice enough fellow so). I think the ending shows a very interesting contrast between Lapis and Diana's the nature of their love for Natori. Diana is somewhat immature and her desire to give Natori up is clear not something that is entirely genuine but more of an obligation she felt while Lapis' is 100% selfless and genuine. She really thinks that the she will only end up hurting Natori if they stay together and this is why she believes she must let her go.
Is going to be very interesting to see how this will develop in the future, will Natori be able to change the plot enough for Lapis to drop her quest for vengeance? Or will Lapis decide to be selfish for once and keep her relationship with Natori and to hell with the consequences?
Oh, and I still think that Rubeus is gay for Gran.
