"Hands Off" is a gross understatement. She's useless.
Other then being the person to send you to places, she serves zero purpose.
She has zero-combat capabilities and hasn't shown any skills in tactical thinking, strategical planning, diplomacy, or any of the in-game sciences or magic. (At least Tataru balances the books, does secretarial work, and has an aptitude for crafting, in addition to having a charm that attracts NPCs)
The only useful quality she has is the Echo, which she doesn't use until 2.5's ending.

Spoiler
The only time she was of any actual use was going with the Warriors of Darkness to their world, aka leaving use for good so Alphinaud can take her spot as the Scion's leader and Krile as the Non-Player Echo user.
