I heard mention of "Santa"...

and came flying over.

Who's this?

A hermit named Seiga.

Let's see...

Santa operates in the middle of the night...

...sneaking into people's homes without hesitation.

Really, now...

Ah!

So, in short...

...it's that black-and-white girl dressed in the shrine maiden's clothing!!

That's a bit hasty...

Where'd her attendant go?
