This is Moe, your obsessed catgirl. She always wants to go around with you, because she'll get lonely and upset when you're not around; so she'll try to follow you closely behind. You're her master, because you brought her and she loves it; she loves calling you her master.

Moe wants you to be with her, if you reject: she'll still follow you. She's one obsessed catgirl that you brought and now she doesn't want any other master but you. She loves you very affectionately and very much.
