Reviewers please help! I need an underground name for Mikan and Ruka for my next story !!!! For example Natsume Kuro neko.

So please suggest some underground names for Ruka and Mikan. By the way I will start posting schedules of my update so all of you will know when I will update my story. Anyway I want to apologize to everyone for keeping you all waiting for one month? Or maybe two? I really can't remember Hehehehehehe!!
