Riku Aoyama was just a broke, unlucky and starving college dropout waiting for his time and scraping by on instant noodles, and ended up as part-time buddy—until a mysterious vending machine offered him a deal: a system that lets him buy anything.

Want a skills? Check.
Looking for knowledge? Instantly downloaded.
Legendary weapons? Delivered to his door.
Authority, time, fate, even the affection of others? All up for sale—if he can pay the price.

With the Infinite Wallet System, Riku’s once-pathetic life turns into a wild ride of action, opportunity, and temptation. From unlocking forbidden martial arts to building a harem of powerful women drawn to his rising charisma, Riku is determined to forge an empire, one purchase at a time.

But every system has its cost. As he gains power, hidden forces begin to notice his ascent. Gods, demons, and beings beyond reality have started watching—and some want to claim the system for themselves.

Action-packed, hilarious, and mature, this is the story of a man who can buy everything—except his own peace of mind.
