It is possible for her to absorb her twin in a certain way.

When there are two twin fetesus in a womb,one could die.Although the chances are high for the other fetus to die,sometimes the remaining fetus would absorb the remains of the other fetus that died.And what usually then happens to the fetus is,they inheret something from the other fetus.This is called human chimerism.And in some cases it can lead to problematical medical conditions.One such occurrence is known as heterochromia,where someone has two different coloured irises or mixed coloured irises.And this can maybe explain why she has a extra kakugan.Although I believe that this could have given ishida the idea of doing this
