Little bit of Emilia's contract with Puck

No Spoilers

Emilia herself explains her contract with Puck is filled up with so many conditions, but most of them are trivial or... well. It also seems Puck freely adds up more conditions as time passes.

Those are not all but few of them.

I will be active only from 9 am to 5 pm

Do not ask my relationship with Beatrice

Do not look into mirror or go near large water

I will choose your hairstyle every morning

Groom my fur regularly

Have some exercise when you wake up and before going to bed.

Do not be picky about food

Talk with lesser spirits every morning and evening

ETC

You could see what most of the conditions are about.
