cirno just realized she doesn't have a family name...

Most fairies don't have last names anyways right?

If only we can have Whiterock Cirno.

If we follow the direction this series has been going, soon she will be Hakurei Cirno.

.. it seems even when thinking about her own name, she mixes up Chi with Sa....

that's a chi, not a sa. it's correct.
