Character Names???

So I've just posted a picture of my main female role now named Kirino.  I really like the sound of that name so I was just wondering if I should give EnlightendShadow a "REAL" name.  There is definitely a reason why he is named that but I would like for him to have a normal name that only Kirino would know.  I've been thinking and thinking but only one name keeps on popping up in my mind and that is Setsuna.  So what do you guys think? Should that be his "REAL" name, should I just leave it as EnlightendShadow since it is already recognizable, or do you guys have any ideas for a cool name for him?  Sound off below
