Banner of the Stars II opens with Lafiel and Jinto speaking Abh (which tricked me too...), just a warning, you may be very confused.
This series, though I haven't seen all of it yet, focuses more on the emotional aspects. Such as the relationship between Lafiel and Jinto. However, this series, at least in the first DVD that I've seen (I've just ordered the 2nd one) is somewhat implying that *Slight spoiler (from the opening sequence/episode)* that Jinto dies at the end */end spoiler*. I am of the personal opinion that this is not true, as if you read the preview text on the third disk (no spoilers in it), it contains these words "And Lafiel must finally come to terms with what is important to her." Which seems to imply a rescue of some sort.. or at least, I fondly hope so. I'd be MAJORLY po'ed if he DID die.
Aside from my personal rantings, I can already tell that this series is going to be one incredibly powerful one. Possibly even better than Banner of the Stars I (which in my opinion is better than Crest, but oh well). Its full of much more emotion then the others, and the voice acting of the main characters has improved yet again (the same difference between Crest and Banner I).
I cannot put this one down, I must see what happens, which is why I'm making the warning that this is as additictive as cocaine.
