And? How did the story end?

In the end, the story was cancelled due to poor sales...

Five volumes were released, but the story was never concluded, and the world just exploded...

Mistress! Young mistress! My apologies for being late! I've brought you cake...

Ahh!!

Sister...

I have never seen someone as useless as you. You didn't even think to bring plates. You even lost against Cirno of all people in the previous incident!

I might as well make Cirno my head maid, instead of you!!

Don't just stand there! Clean this up!!
