Liar, Liar, Vol. 3 (manga)

The stakes just keep getting higher! On the Academy, stars dictate everything, like what Abilities can be used or even one's social standing. And while Hiroto's lie has granted him Seven Star status, he must continue to prove his worth and protect his secret--this time, against the Five Star Seiran Kugasaki, who also wields the power of a Unique Star. In the face of such a high-level opponent, how could Hiroto possibly win, especially when, in reality, he has only a single star...?
