Rena is Shugo's twin sister, and although they are the same age, she can act stern towards him. Caring a lot for her
brother, she believes he'll come through for her, no matter the
situation. Before having to leave home with her mother, she installed
The World onto Shugo's computer without him knowing so she could spend
time with him in the game. Rena plays as a chibi version of BlackRose, a
Heavy Blade, which she won in a character contest.
