Here you'll find general information about Minako and Zoicite. There aren't that many spoilers here but if you are truly picky or really don't want to be spoiled, then please proceed with caution.
Aino Minako / Sailorvenus Played by Komatsu Ayaka
Even to the outside world Aino Minako is anything but ordinary. She is a famous idol, living a hectic life of modeling, radio appearances, recording and performing. Somehow Minako has managed to fit being Sailorvenus into her busy life. With her life as Sailorvenus came responsibility and a strong will to protect the princess and finish the mission that was started already in the past. Out of all the Sailor Senshi, Venus was the one who received her powers and memories first and in order to trick lure the enemy away from Usagi, posed as the princess for months. As the leader of the Senshi Minako is very strict for her age and to her the mission from the past means more than everything, even herself as Aino Minako. Her most constant companion is Artemis, who acts as a mentor, guide and, perhaps most importantly, friend to Minako.
Zoicite Played by Endou Yoshito
One of the four Shitennou, Zoicite was clearly different from Jedite and Nephrite from the first moment he appeared. He is mysterious and somewhat aloof, spending a lot of time in his own private room with his piano and hardly ever coming before Beryl even though he serves her. He has been assigned by Beryl to find the princess and, using his music as a way to channel his powers, he mentally searches and follows Minako, who is believed to be the princess. Later on Zoicite's mission changes, as his master returns his new agenda in life becomes to protect his master from both the Senshi, the other Shitennou and Beryl. Like Minako, he has memories of the past and tries desperately to stop the past from repeating itself.
