Demon in disguise

Different from the rest

It has been 3 days since the killing game started and monokuma tells everyone that new students have been accepted into the game. The 3 walk in but there is one of them that caught your attention. She has long black hair,a light blue dress on and she's very strict. "Everyone meet mittuki,sirena and Luna" monokuma said in a voice that sounded way friendlier then normal which proves he's planning something. "Great more people to join D.I.C.E" Kokichi said as usual he was very different but you couldn't help but look at the girl in the light blue dress. Just then she walks over and introduces herself to you "h-hello im Luna it's nice to meet you what's your name". She's about 5'4 a little taller then you.
"Oh my name is Y/n it's nice to meet you too Luna" you say trying to not seem suspicious but something was off about her and you don't know what. As she left to talk to Kokichi you noticed that she was very.......interesting she would always mention things about the game to him and it was making you suspicious of her and why she's here.

(Time skip to free time)

During free time you noticed Luna constantly with Kokichi or Gonta but with no one else and she would always stop Kokichi from doing anything stupid or bad. Just a couple minutes later Kokichi and Luna run up to you with a flower crown and put it on you then run off. You take it off your head and you put it in your back pack you obviously think it's some kind of prank because Kokichi is involved with this. After another hour free time ends and it's class time. You start to think what could be Luna's ultimate because she never said it and it's completely random and how she acts she acts like a child but you continue to think until class time is over.
