Implicating Code Geass: Nunnally in Wonderland -> Code Geass.

Reason: It is the Code Geass parody of Alice in Wonderland. The same characters appear in both.

I suggest keep Nunnally in Wonderland same as we have Idolmaster and Idolmaster: cinderella girls. Just like that.

Implication not alias.

If I am not mistaken, Idolmaster Cinderella Girls does imply Idolmaster, which is consistent with my request. ;)
