So second day with the Princesses.
I unlocked Trisha's love scene at Level 15, and she is just too damned sweet and adorable to stand. I'll need to get Meryl to 25 (which WILL necessitate getting enough shards to up-star her) so I can compare the two -- I always did like the more amazonian blood-knight types.
I got my hands on some Collegiate Water Scrolls from a Vessel Summon (would have preferred another girl, but you take what you can get) and used it to skyrocket Isabel, my first three-star girl, into my main ranks at Level 15-16. I've not taken her on missions yet, as she's currently on cleansing duty at Aphrodite, but if her performance in the Tower before she got taken down is any indication (the word "beast" would be appropriate if not for the fact that that's the name of the main enemy of our girls -- she wrecked the first two levels all by her lonesome before being taken down by the girls of the third level), she's going to be one of my mainstays.
Still haven't gotten an Air girl, which is pissing me off big time, not the least because the grand majority of the second act had me defaulting to other people's Air girls to clear out the nasties. It was like the time I had to go Riderless for much of early FGO before getting my hands on Alexander. I still haven't decided on which archetype I want to use (and thus which girl I want to build up shards for).
