Liar, Liar Novel Volume 5 was written by Haruki Kuou with illustrations by konomi.

After making it past the May Interschool Competition, Hiroto Shinohara—that's me—is enjoying a nice little break for a change. Then comes along a challenge from a girl who's all too familiar…the whole reason I came to the Academy, in fact. Beat her in a Game, she says, and she'll agree to meet up. So I decide to bring this up with my provost—only to get dragged into a special Game against Saionji, with a purple Unique Star on the line. They call it a “Game,” yeah…but the theme's all about love? And I'm being asked to pick up romantic lucky charms and solve relationship problems for people?! But if that's the challenge, so be it. I'll just rely on the Company and break out some classic Seven Star Abilities—but hang on, is Himeji angry at me about something…?
