Robin

Simon's adopted daughter studies to be a theoretical mage, summarizing it in saying that she doesn't throw many fireballs, she designs better ones. (Though this certainly changes after she joins the party.) She has conflicting emotions regarding her father's situation but it doesn't take her long to accept it and adapt to the new situation.

Story
A young student in Thaumaturgical Academy, she was adopted by Simon as an orphan under circumstances not yet revealed, at "elementary school age", years after Wendis's death.

She is a very reflective and private person that doesn't give her opinion if she is not sure, she has the potential to be a great mage both in theoretical and real-life situations, if she can defeat her own insecurities. Even after embracing a life of adventure and risk, she is always interested in the investigation and theoretical aspects of magic.

So it's not only natural but logical that her father trust her when there are delicate matters, such as the investigation on Trin's powers or the management of the old armor. In any case, Simon is not the only that seems to appreciate her talents. Not only she is well considered by her teachers and peers in the academy, but Riala, a competent and well educated mage on her own right, also shows her admiration and offers her a tutorship.

Robin starts off sharing a room at the academy with four other students: Interactions with her schoolmates will likely happen in a future update, if at all. (Sierra has stated that you *may* get to humble Mherin later).
 * 1) Mherin - the world's least grateful rescued noble. (Possible tsundere type).
 * 2) Rachila - the stuck up new money tycoon's daughter.
 * 3) Infasis - token slutty schoolgirl.
 * 4) Sho - ultra shy friend type.

Joining party
Talk to Megail about partnership. Then go to sleep. After Simon departs on an unspecified errand, she arrives and has a funny conversation with the rest of the party. After all the talking is done, visit her at the Academy (and enjoy the antics of her classmates). She will join you at the start of the Simon's Daughter quest.

You should recruit Hilstara then go to the Academy instead of entering the mine, for maximum XP.

Tactics
She is a strong wizard type. Although she has some capabilities as a healer, she lacks any offensive or support AoE spells, limiting her usefulness in battles with a large number of enemies. She has a larger reserve of Mana than Qum does and her healing spells cost half of Qum's, so she is a more efficient choice for out-of-battle healing.

Relationship points
Maximum affection is 100, at which you can have a conversation with the harem girl that will lock her affection there.

Not much offends Robin, but her close starting relationship with Simon means that it's hard to raise her affection as well. So far her most significant boost is the potion license quest, with others centering around using her for research. Her only two point losses suggest she may have issues with her father bedding random women.
