Who cares about age, you're beautiful Eirin, and that's all that matters.

I can't help but think Eirin attached her own head to Mami's headless body through some horrid surgery process, in an attempt to 'regain' a 'young' body.

Oh, you...

There are other, more efficient ways to do that. Shady drugs, for example.

Well either it is now magical girl Eirin (using Mami's body). Or Mami, when she gets "old" will become "Eirin".
