In March 2010 as part of the Nitro+CHiRAL 5th anniversary an anime adaptation was announced for Togainu no Chi with production by Aniplex.

To participate, one must go to Toshima's palace, meet with a man named Arbitro, and tell him the reason for their decision to enter into Igura.

(The game incorrectly refers to such a Straight as a Royal Flush, which is a poker hand that requires that all cards be of the same suit.)

If a participant collects a Straight or Full House consisting of the tags representing the cards 10 through Ace, they earn the right to challenge Il Re in battle.

If they defeat Il Re, they assume his position in distributing Rein and become incredibly wealthy, which is the primary motivation for many of the fighters who join Igura.

After some time in prison, a mysterious woman and man involved in the government visit him, offering him freedom from his sentence if he agrees to participate in Igura and defeat Il Re.

The story follows Akira's life in the harsh, lawless Toshima as he fights both to survive and to unravel the mysteries developing around him.
