Yes. I’m Sailor Mars. They all call me “Flame Sniper.”
Are you ready?
Burning without making a sound; to me that’s the best way to do things
I have to strike ahead of the foe Love and Battle; to me they’re both the same
And even when I dream my heart it blazes with a fire ardent
If I ever think “I want it”, I have to snatch it away and make it my own
Lyrics Translation by Anime Lyrics
Anyway, if anyone knows who the cosplayer is, please let me know! Thanks again to Shuichi for sending this in!
