Been sitting on this all day. Commerson's Dolphin is as follows:
>Miracle: Damages one enemy, increases all allies' damage done by 16% for 3 turns, and increases all pink allies damage done by 20% for 3 turns.
>Beat: Damages one enemy, and increases own MP by 5. If the stage has a water theme, there is a high chance to decrease the target's MP by 5.
>Standby: Removes the MP Reduction state from pink allies, and generates 10 MP. 100% activation, 2 activations per battle.
>Wild Release: Increase pink allies' resistance to the Dazed state by a high amount, her own damage taken is reduced by 15%, and she recovers 2% stamina every turn.
>Photo: Increase pink allies' damage dealt by 10% other than herself, and restores 3% of their stamina per turn. If the stage has a water theme, all pink allies gain 10 MP at the start of the battle.

Commerson's Dolphin splashes onto the scene with today's story update. She brings with her some decent support for pink friends, producing a large amount of bonus damage once fully upgraded. She also comes with a surprise damage boost for all other friend attributes, which makes her somewhat viable in a mixed attribute team. Her miracle does not give pink allies a total of 36% increased damage, and her standby skill likely means the Dazed state since Google translations sometimes don't translate well.

Commerson's Dolphins are listed as Least Concern in terms of conservation, meaning they have a healthy population. This breed of dolphin has a rounded dorsal fin, and is also known as a "panda dolphin" due to their coloration resembling a panda's. Most interesting of all is that this breed of dolphin is one of the smallest dolphin breeds, with their current max size being approximately 1.8 meters long. There are smaller dolphins, but Commerson's Dolphin is very small!

The new story chapter is out, and you can get 195 urchins by completing new story quests on both difficulties. Normal difficulty quests have no stamina cost for now, as well.
