cherry blossom crystal

how do I get cherry blossom crystals I need 25 for the magical device for my storm mage but I can't find them anywhere :/ the quest only gave me one and I can't Replay it

 

Um... I get like 11 in total from clearing Easy, around 50 for Normal, and 260-410 for Hard. And its repeatable...

 

They come from the Chapter 3 Hinami quest. Its repeatable, but the amount you receive lowers each time you repeat. as MAER said, you can gather a large load the higher the difficulty, but if you cannot beat the bosses, you can also just constantly play the selection portion of the quest. on Hard, that should net you about 12 gems before the boss. Then just quit quest, leave the venue, and do it again.

 

Just some extra info tho, the amount of crystals you get once you beaten deniala is determined by how many clues you got correct. Also if you got the 3rd clue right but got both the 1st and 2nd clue wrong you'll still proceed to deniala.

 

I haven't completed ch3 I see now no idea what to so
