Spike figured things would be routine once he moved out; a job, home, relax, bed, rinse and repeat.
That is, until he somehow became the adopted older brother to a rambunctious group of little girls...all of them with a habit of calling him by 'Onii-chan', but that's not so bad, right? And he managed to get hold of a place big enough for them all.
Now if only he could figure out where these small technicolor horses keep coming from...
And why they're so cuddle hungry.
