Formerly a graduate student majoring in psychology, he is a "genius swindler" who took down a giant MLM scam named Shuuei to avenge his mother. He helps Nao when he sees the honest nature she had, just like his mother. Although he is not invited into the Liar Game, he enters by substituting for another player in Round II. By Round III he is respected (and feared) enough by the LGT players to become unofficial leader of the Southern Country, though he tries to keep things equal in the group. Yokoya, however, knows Akiyama had been manipulating his team mates and mocks him for it.

Wishing she would live up to the ideal, Kanzaki Nao's father named her thusly for &ldquo;honesty&rdquo;. Nao has more than lived up to her father's wishes--even exceeding them and earning the label of "a foolishly honest girl". This makes Nao the least qualified candidate for the high stakes 'Liar Game', where winning requires deceiving the opponent out of their money and losing means receiving massive debt. However, that doesn't stop a box containing a hundred million yen in cash and a card informing her of her participation in the game from arriving at her doorstep, nor does it stop her from being promptly tricked out of the entire sum of money. Upon hearing that a genius swindler, responsible for the bankruptcy of a major corporation, is being released from jail, Nao goes to the swindler, Shinichi Akiyama, to enlist his help. With that, the two are drawn into the dark, greed-filled, and deceptive world of the Liar Game.


A collection of short stories by Kaitani Shinobu.
 
1. LIAR GAME roots of A 
Roots of A is essentially a manga short 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. 
2. Nine Darts (ナインダーツ) 
3-4. Sansou: Kindan no Senjutsu (サンソウ～禁断の占術～, Three Phase: The Forbidden Divination) 
5. Kaitani Shinobu no Aiken Monogatari (甲斐谷忍の愛犬物語 , The Tale of Shinobu Kaitani's Dog) 
6. @Lovers (@ラヴァーズ)

After being inspired by Professor Yukiya Okabe, fourth-year student Shinichi Akiyama has decided to pursue graduate studies to learn more about the human mind. While Akiyama is having a one-on-one consultation with the professor, a faculty member from another department, Mitsumasa Iwashita, interrupts the two. As Iwashita urgently requests to discuss an important matter with Okabe, Akiyama cuts his consultation short.
 
However, that does not stop Akiyama from eavesdropping on their conversation. He overhears that the science entrance examinations have been stolen, and one of his close friends, Kouichi Aratani, is accused of being responsible for this occurrence. Having known him since high school, Akiyama believes that his peer would never commit such an offense. With the guidance of his professor, Akiyama goes through every possible detail in this exceedingly intricate case.
