Synopsis
Harei Aine, a childhood friend of the ace of the table tennis club, disappeared. He will fight in a back gambling house hosted by a rich man to repay his father's 80 million debts.

The gambling is "dark table tennis" where girls wearing Gothic Lolita clothes bet a tremendous amount of money to win or lose.

Osamu Sakai, who searched for Harei and arrived at her forgiveness, challenges reckless gambling with a life bet in order to rescue her childhood friend from debt hell.
