April showers bring May flowers.
Chise is an unwanted child who is passed from home to home. Since childhood, she has been able to see creatures others could not, and because of these powers, was seen as strange. A man confronts her, giving her a chance to be taken in by someone who would want her. Though it is unknown why anyone would want her, she is sold off for 5000 pounds to a sorcerer named Elias Ainsworth.

He teleports her, in a flurry of thorns, to Britain where he offers a comfortable life. Gifting her a cursed stone, he decides to take her on as a magical apprentice, and just as abruptly, his wife.

After explaining what magic is and sends her to bed. Against a window, a faerie she had met briefly leads her on a walk in the mountains and attempts to take her to her land. Chise declines the offer, choosing to stay with Elias, the first person who called her family.

One today is worth two tomorrows.
Morning dawns, and Chise is greeted by the Silky, Silver. After breakfast, Elias takes her to their honeymoon, which in actual is a glorified errand run. They enter the shop of Angelica, a sorcerer known as a magic technician. After Chise mentions that Elias tore her clothes off, washed her, then porposed to her in the span of 3 days, Angelica punches him in the stomach and leaves him at the front of the store. Alone with Chise, they try to experiment with a crystal. Chise quickly creates a gleaming field and Angelica scolds Elias for keeping Chise's status as a Slay Vega secret. Elias commissions something that can hide Chise status as a Slay Vega from faeries, and lets Angelica continue working on the other things he had commissioned.

The scale distinguishes not between gold and lead.
The church sends the two protagonist on a mission to the cat kingdom. Chise awakes in a train and learns that cats have nine lives from a talking messenger cat. Long ago, a man killed many cats for their lives until the cat king joined the remaining cats together to devour the man. The remains of the man remain in the form of a stagnation, a soul that cannot leave the earth.

At the pond where the stagnation was left, Elias asks Chise to purify the stagnation, however Chise is hesitant, having heard a strange women speak to her saying the only way to get rid of the stagnation was to erase her soul.

Everything must have a beginning
Elias and Chise arrive at their destination. The cat king greats them, and guides the two of them toward a pond where the stagnation lies, an impurity that exists to devour life. A strange figure catches her by the arm and pushes her into the water.

Misfortunes seldom come singly.
Potential drowning, Chise imagines the form of a women that calls herself the core of the stagnation. Another person is clinging onto her and will not let go. Before Chise wakes up, the women tells her to kill her.

Soaking wet, Elias is once again by her side. They wait for night, the safest time to perform the purification. A staff with a lantern is handed to Chise and with the help of an fae, she is tasked with purification. Before she can start however, the figure from before and a man named Renfred hold her to knifepoint.
