Do you really think the world is ready for there to be two of me?
No, definitely not.
Ahem...I am trying to fathom the mysteries of this world, 2 Cirnos == Heaven for Gen while Hell for others. :p
More like Heaven for everyone, Hell for me.
What if the two had the personality split as well: One that is tsun, and the other dere? 
Knowing me, they'd both be Yandere. Just imagine if one was possessive and the other was obsessive Yandere.
