Big Brother is kind to Guest.
He never laughs behind my back calling me "dregs," nor does he look down on me as a "disgrace."
He doesn't get angry when I fail, he watches over my training, and he shelters the displaced Guest in his home. There are fluffy blankets and delicious meals. Big Brother strokes my head and tells me I'm a good child...

...But. But. Why, why do the tears fall like this?

Disowned!! Guest cannot even get a decent meal on their own.
Where should I go?
1. Human Realm. Get essence on my own.
2. Demon Realm. Ask Big Brother for help.
3. Other. ???
