Aventurine Wave... Should I pull for this character?

As it's the path of Joyful Destiny, it seems to have great synergy with multi-hit parties. If your characters have many attacks, it's definitely worth considering.

Hmm... it's a bit ambiguous just from the description lol. It seems good that there's an extra attack every time the whole party attacks... but I'm not sure if it's a must-pull ㅠ

The 'Ecstasy' skill gets stronger with each passing turn, so it seems like it would be good for boss fights... But I think people pull for the character's visuals more than anything.

She's good for a chase comp. But if you don't have Blade and Ashveil, is it really worth it?

If you have Blade or Ash, I recommend pulling for them.

Ah, he's so handsome... but if he's not your type, there's no real reason to pull for him.

Even if it's not a chase-attack team, whenever an ally attacks, Aha's speed increases and stacks build up, so it can be used with Archer parties or Anaxa parties that have many hits. Conversely, even with just 3 supports and one Suerchu, the damage is good (requires SP management) if crit rate, crit damage, and speed are well-balanced.
