Hello! The life-form you are currently speaking to goes by many names, but the name you shall know Moderator One by, is Kyubey.

Upupupupu~! And I'm Moderator Monokuma!! Welcome to Hope's Peak Academy for the Ultimate Students.. And MAGICAL GIRLS?!!? SUCH EXCITEMENT!! 
Me, and my dear friend, Kyubey, have thought of this Despair-filling idea! Pretty Fighting Girls joining us to kill each and all students in the school?! That's incredible! 
Now, I must go now! Upupupupu!!~ ♡♡

Yes, Moderator Two, also known as Monokuma, and I have devised a plan to put my Puella Magi and his talented students into the same situation. Hopefully it will cause my Puella Magi to despair even faster! Their Grief seeds combined would stave off the the heat death of the universe for quite a while!
