Below is what I currently know about increasing Amaterasu's friendship:
1. Additional Titles and increased max number of titles
2. Grants Bonus Status Points @ friendship levels 9 and 10 (I think, there might be more on later levels as well)
3. Adds bonuses to player and ally abilities

Are there anymore? My Amaterasu is only level 10 so I still don't understand much about her. What kind of bonuses does she add to player and ally abilities?

Other way around. Amaterasu bumps up Shizuka's identification strength. xD

Note the (+1)

oh lol I see what you mean now, my Yoshitsune also has a +1 on Repair skill so that must be thanks to Amaterasu as well
