Thoughts about Yuno's "twin"
1. Yuno is a twin by birth (I hope not)
2. She is a clone (she was in a cage after all in one chapter)
3. Something to do with time travel/ alternate dimensions (There IS a god of time you know)
4. One is real and dead, the other is an impostor who dressed up as Yuno (highly doubt)
Also, Akise may be gay or he may not (leaning towards gay). Even though he kissed Yuki, he may have planned it to enrage Yuno or he wanted to follow what his diary said, because it claimed that he could kill Yuno.
