Miss Witch's Forbidden Book Secret

"Ms. Tia Sulph, what was your original intention in becoming a witch?"
"Debt collection."
"No, you misunderstood. I meant your ultimate goal of becoming a transcendent, embarking on the path of alchemy, establishing a secret society, and becoming a leading figure on this path."

"Collecting debts together."

"A debt of love is also a debt."

"So, do you need business? 70:30 split."
"Well, I have a creditor here who owes a large sum of money..."
"rush!"
