Aliasing tachibana_tomoe -> tomoe_tachibana.
Well, her name is written in Japanese as "トモエ・タチバナ". (Profile on the Japanese Trauma Team site: http://img205.imageshack.us/img205/7990/tomoetachibana.png)
(The Japanese might not even be applicable, since the game was released first in North America. In the English version, she's "Tomoe Tachibana" as well.)
But on the other hand, it's clearly a Japanese name, so maybe the alias should go to "surname givenname" order regardless of what the source uses.
