Spending Money Makes Me Invincible! From the Start, I Planned to Slay a Dragon

On my first day abroad, I got mugged! With nowhere else to turn, I met a gorgeous young woman with fair skin and long legs. Little did I know she was rotten to the core.

Young people, stay away from gambling. By the time I learned that lesson, I'd somehow become the owner of a mysterious shop.

The shop has a cool succubus who looks at me with utter disdain, underlings itching to cause trouble, and demon lackeys who collect a paycheck without doing any work...

I can't back down. Spending can change my fate, and mysticism can save my luck. My destiny is mine to control, not Heaven's!
