Okay so Ino's gimmick, apart from being an evade Defender and having Arts and Skills that get boosted every time she gets KO'd, is that she's tied to a resource called "High Ether". Separate from normal Ether, it only shows up with the DLC unlocked, and you'll have to get a bunch to apply to a skill tree called "Inoswap" that's similar to an Interlink Soul Tree. It's got the usual stat buffs, skill buffs, and art buffs, and there's a second stage only unlocked when you complete her Ascension Quest.

For each High Ether spot you found, a new one gets put on the map as a "hint", so you kinda have to find them in sequence. I'd suggest the minute you get the hint to mark the spot, because there's no icon otherwise.

Also, *slight spoilers* Ino's an artificial Blade, like the ones in XC2. After Noah tries out her class during a cutscene, she names him her Driver. And they're all like "what's a Driver" and Ino's like "you fight by my side" and everyone's like "Uh, that's it? Sounds kinda dumb when you put it like that."

EDIT because I was wrong about High Ether. You have to follow the hints, but you can still see it in the field if it's there.
