Lieutenant Takahashi Riku
Takahashi Riku was a Starfleet linguist and protocol officer until he resigned in disgrace some years ago. While the details are not widely known, it is broadly believed his resignation was the only thing which avoided an unpleasant and messy public court martial. Since then he has worked for the Earth Cargo Service, which reportedly better suits his irreverent approach and lack of respect for policy, attributes which often brought him into conflict with his past superiors. Only at the direct request of Captain Lopez has Lieutenant Takahashi been brought back into Starfleet to serve on the Phoenix NX-08.
