Liar Liar 14 (MF Bunko J) [Light Novel]

[Machine Translation] I, Hiroto Shinohara, was troubled by the heinous situation of the third semester school district tournament - Harutora Koshichi's trickery using the "scenario writer" and the outburst of the Izumi sisters' "Pluto". What appeared in front of me was a girl, Shion Hagoromo, who should never have appeared on the school island. If things go according to the enemy's plan, "Our Lie" will come to the worst possible end. If this is the case, then Eimei Academy has a chance to win if we tell a lie that can only be told under these circumstances, involving even Hagoromo. The only thing that can counter Ochi and Izumi's cheat-like abilities is lies, cheating, friends, and my own strength that has gotten me through all the devilish battles I've been through. Let's see the secret plan to reverse the situation.
