Large Cylinder Ruins Tree
Small Cylinder Ruins Tree
Circle Ruins Tree
Triangle Ruins Tree
Face Ruins Tree

I have had great success with:

Triangle Ruins Tree -- [S63 / I5~48]
Circle Ruins Tree -- [S5 / I8~58]
Large Cylinder Ruins Tree -- [S42 / I23~25]
Tiny Ruins Spider -- [S5 / I2-46]
Ruins Spider -- [S18 / I13~14]

I was able to get her to 800 amity in only 3 conversations using this combo.

Assuming you have all topics:
(topic set - topic #)
(2-3)
(1-2)
(3-5)
(2-2)
(2-1)

You can just go with whatever is the highest interest with the highest favor and be sure to sandwich some of the 75% in between the 100% to raise them as the 100s will lower too. I couldn't get many points out of the games with her, often getting low scores and fail to spark. I just F5 for the last couple hundred amity.

Triangle Ruins Tree
Ancient Ruins Defender
Face Ruins Tree

This way you'll likely get favor and combo from all of them (all above 40% chance).
