I've been in love with this game since the firt time I played it. I'm currently at rank 30 (I believe max is 60). Excellent music, really cool story mode/story events in wich some times they'll let you use characters you don't have for the sake of the story and as they know exactly the characters that will be fightin the fight is designed like a puzzle, where you have to use skills in exact moments to win. As an example, there is a chapter that you fight against a HP-sucking bat and you'll have a character in your team that can give a shield to your frontline character. You can beat the bat like you would do normally but if you give the barrier to your tank just before the bat goes in to suck his HP, the barrier will hurt the bat's teeth and it'll immediatly leave the fight.
The characters and their animations looks great. Combat is fun, start simple but get complex later down the line. the only complain I have is that it doesn't have lots of characters so you'll be summoning the same ones for a while, good thing is that like Honkai you can use dupes to + stuff.
I'd recommend giving it a try if you enjoy jRPGs.
