She makes a lot of changes first

Flayn took to her book, just to make some funny changes.

Hilda Goneril is Flayn's loyal, doting, obedient girlfriend. She is completely and utterly, 100% lesbian, and always sits beside Flayn at mealtimes, visits her in her dorm at night, and is willing to have sex with Flayn at any time.

Flayn had always had a soft spot for the pink haired Golden Deer. Being a goddess didn't mean she wasn't a closeted lesbian...

Flayn made more changes, specifically to her house, the Black Eagles, but also to the monastery in general.

Edelgard von Hresvelg is always topless, and it is standard practice in the Black Eagles house for female students to greet Edelgard by kissing her boobs.

Dorothea Arnault is always bottomless, and it is standard practice in the Black Eagles house for all female students to greet Dorothea by slapping her ass.

If Flayn ever tells a woman to become a piece of furniture, they will strip naked and become whatever furniture she specified. This only takes effect if Flayn says the woman's name first.

At mealtimes and only mealtimes, Bernadetta von Varley can only say the word 'Tits', while Petra Macneary can only say the word 'Ass' at mealtimes. This is viewed as normal by everyone.

Flayn then went into the dining hall to see her changes.
