Jilted by My Fiancé, I Choose to Return Home and Farm [Crossover]

The setting comes from the game Stardew Valley. It's fine if you haven't played it, just let me tell you all about it.

The heroine looks like a little girl who never grows up. She's a good-for-nothing witch who loves farming, chopping trees, and mining.

Her three familiars never listen to her: the former Count of Poisons, Cain Harris; the former queen's watchdog, Ciel Phantomhive; and the former Red Dragon of Britain, the Azure-Silver Knight Arthur Pendragon (Saber).

The everyday life of Kiriya, a little witch who never grows up, as she tends her fields with a tiny hoe.

Kiriya: I have three familiars. Two used to be human, and one wasn't, but none of them listens to me QAQ

Witches are nightmares to many planes, the embodiment of the demons deep in humanity's hearts.

Devastating gales, beams of light that lay siege to cities, the madness of falling stars: the most magnificent disasters come from the mightiest witches.

Summoning witches soar through the sky on dragons, fire witches laugh aloud in raging seas of flame, and shadow witches sneak through the darkness.

Kiriya, a witch naturally gifted in both earth and wood magic: Excuse me, I'll choose farming :)

After being dumped by a prince and facing a graduation crisis, the inept witch can only return to her hometown to farm.

The author has a guilty pleasure for these clichéd broken-engagement plots.

Every handsome male character has a one-sided crush on the heroine.
