Effects of player actions
If you're a friend to the Followers of the Apocalypse she will discount the cost of her supplies, but implant prices remain fixed.
She will also pay full value for items in your inventory if you're a friend to Followers of the Apocalypse, although she only carries 2400 caps.
If the player has Intelligence of 3 or below, Usanagi will give the player a discount on the Intelligence Implant out of pity. This relates to unmodified base S.P.E.C.I.A.L. Intelligence, so temporarily lowering Intelligence by chems does not count, but gives the special dialogue options ("You sell plants?") with no other effect.
Caps paid for implants will not go into Doctor Usanagi's inventory for bartering purposes.
Notable quotes
"We believe that technology for basic necessities, like food, water, and medicine, should be shared, not hoarded. We're also strongly in favor of proper education. I've come across more than a few "doctors" whose techniques came out of the back of a magazine."
"I have reserved a small part of my supplies for sale. The profits go directly to the purchase of additional supplies to help the less fortunate."
pc Although Usanagi will ask for donations to the Followers of Apocalypse, a buggy script checks her inventory instead of the player's for the required caps, thus preventing donations from being made.
xbox360 Sometimes the dialogue option to ask Doctor Usanagi to heal you will disappear entirely, rendering it impossible to regain health or heal crippled limbs by her.
