There is a very strange restaurant in the City of Sin.

Elves and dwarves must share a table, orcs are strangely well behaved, dragons are only welcomed on the small square in front of the restaurant, and the demons must bring their own stool.

This strange restaurant with their strange rules continuous to attract a long line of customers.

“This place serves the best food! The chef of this restaurant is a genius!” Some of the guests in the restaurant left glowing reviews. But these guests have a word of warning for other guests, “No matter what you do, never, never attempt to kidnap the boss or try to ‘eat and run’. You will die.”

A cute little girl stood near the door, and demanded in her tiny voice, “You have eaten the food, now pay up, or I will beat you to death.” The five-meter tall dragon suddenly felt a chill running up its spine.

Caught up in a ritual performed by a deity of another world, Eiji Choukai was then transported to another realm. The otherworldly deity responsible of the ritual looked at Eiji’s potential incarnations and quickly pulled out Classes like those from, “I Reincarnated Into a Vending Machine.”

But it seems the Classes available for the average person was not available to him. Only the “Parasite” Class was shown.

Without choice, Eiji grudgingly choose the Parasite Class.

His reincarnation into this new world seemed somewhat despondent, but after using his newfound powers, he suddenly realizes its true potential. It seems he’s able to amplify himself countless times by obtaining the powers of others. This luck of his was too good to be true. Seems his level might rise a little bit too much.
