If you had a loved one killed by someone, could you allow that? Could you really trust today's judicial system? What would you do if you had the ability to punish people severely? From the author of Liar Game and One Outs comes a two-part one-shot about a judicial system for criminals that operates under the ideals of, "An eye for an eye".

Sonokawa Junpei is a 19-year-old who works multiple part-time jobs to support his little sister and unwell mother. One day, he discovers a major cash prize at the company where he works as a janitor, V Line, for anyone who can discover the cheating method of a major champion (a user named 'M') of their online mahjong game. As it happens, this same 'M' shows up at the family restaurant where Junpei also works, and Junpei jumps at the opportunity to get money for his family!

His strategy is to befriend 'M' (whose name is Mizuki) and uncover his cheating method. When he goes to Mizuki's house, though, it is clear that the befriending part is going to be a challenge. He learns from Mizuki's older sister that he suffered head trauma in the accident that killed their parents. Since then, he has lacked the ability to experience emotion, though he has also gained amazing powers of memory. He spends all of his time playing--and winning--online mahjong. Now, Junpei wants to genuinely become Mizuki's friend, and to help prove that he is a genius, not a cheater!

Kojima Hiromichi is the ace batter of the Lycaons - a notoriously weak baseball team that is often ranked at the bottom of the league. Determined to lead the team to victory prior to his retirement, Kojima takes a trip to a training camp in Okinawa, hoping to discover what factors the Lycaons lack.
Here, he happens upon a game dubbed "One Outs" - a gambling derivative of baseball - and is soundly defeated by a blond pitcher named Tokuchi Toua, who is claimed to have never allowed a hit in any of the 499 games he's played.

Kojima realizes that he has found the 'missing factor' and makes a wager with Tokuchi. Little does anyone know that the outcome of this gamble will dictate the fates of the Lycaons and all those connected to the team.

Roots of A is essentially a short manga featuring Akiyama during his senior year of college. In it, Akiyama and four of his classmates are taking a criminal psychology course and given an assignment where they must construct a profile of a person based on a letter they sent. This outcome of the assignment, plus what the professor says afterwards, is what prompts Akiyama to enter grad-school and continue to study psychology.
