Liar, Liar, Vol. 4 — Haruki Kuou

AN IMPOSSIBLE COMEBACK!
The May Interschool Competition has been thrown into chaos by the Chameleon, a cheater able to impersonate anyone in the Game. Hiroto's team has managed to stay in the running, but only just barely, and Hiroto himself has been eliminated. However, the lying transfer student claims this was part of his plan. He's uncovered the secret behind the Game, and it's time for a counterattack. Can Hiroto really win a competition he's already lost, though?
