    Karin Osaka/Sailor Sedna (OC)note   
I'm always one known for giving insightful and inspiring speeches. I don't know where it comes from, but from the heart I guess. Then again, being around the likes of Sailor Moon, Yugi Muto, and Takato will do that to you. They're such inspiring figures that I get inspired to be as great as them.

Then, her soul is transported to the Nexus to meet the Lady in White and granted a new body in preparing her role as a dimensional traveler. She was trained in secrecy with Sailor Pluto. In Season 2 (Invasion of the Rajita), she introduces herself to the Planetary Senshi during the fight against the Rajita invasion.

Karin and Dimitri currently live together in a condo, the former works as a full-time museum curator. Kensuke has also moved in her sister, brother-in-law, and niece (Athena).
