Selling Jars at Hogwarts: From the Start, I Give Away the Philosopher's Stone

After transmigrating to the Harry Potter world, Rosen awakens the Jar Merchant System. His jars can yield all kinds of items from the Myriad Worlds.

He can also buy exclusive jars. All he has to do is earn money and open them to grow stronger with ease.

And so, an unprecedented shop opens on the grounds of Hogwarts.

Poké Balls, Devil Fruits, the Twelve Talismans... One precious item after another from other worlds.

They send shock waves through the Wizarding World!

Hagrid: I've wanted to raise a dragon ever since I was little. Thanks to Mr. Rosen's Poké Ball, my wish came true.

Professor McGonagall: One bite of a fruit can make you an Animagus. That's the power of the devil.

Snape: Lily, for your sake, I'll find a resurrection item, no matter what.

Voldemort: The secret to immortality is hidden in those jars.

Dumbledore: Mr. Rosen is a great wizard. I'm honored that he chose Hogwarts back then.
