Just like Haruka and Aoi, he attend St. Cherine. He is one of the most popular boys in their school due to his looks, and it is seen that even Haruka has a few feelings for him.   Yuito can also transform into Misty Knight, and usually comes to help when Twin Angels need help. Yuito Kisaragi is parallel to Sailor Moon's Tuxedo Mask (Mamoru Chiba).    ~!He 'dies' in the tenth episode due to explosion, however, in the last episode (12), he appears again, showing that he actually didn't die from the explosion. !~

Haruka Minazuki and Aoi Kannazuki are freshman high school students and best friends. During the day they help with school activities but at night they thwart enemies like Black Auction and other villains as Red Angel and Blue Angel, the Twin Angel team.

Haruka Minazuki and Aoi Kannazuki are two students at St. Cherine academy. Haruka is always filled with bubbly energy while Aoi is more mature and a top student in all her classes - but despite their differences the two are the best of friends. The two girls look like any other girls, attending the academy, but the truth is they are hiding a little secret, that they can't let anybody know about... 
During the day they really are just students at St. Cherine academy, but they can also become the Twin Angel duo, and fight against the evils of the town! 
The lovely Angels are back, and it's time for them to get ready for some action!
