We show that for each c_M ∈ [ 1 , 25 ) ${\mathbf {c}}_{\mathrm{M}} \in [1,25)$ , there is a unique metric associated with Liouville quantum gravity (LQG) with matter central charge c_M ${\mathbf {c}}_{\mathrm{M}}$ . An earlier series of works by Ding–Dubédat–Dunlap–Falconet, Gwynne–Miller, and others showed that such a metric exists and is unique in the subcritical case c_M ∈ ( − ∞ , 1 ) ${\mathbf {c}}_{\mathrm{M}} \in (-\infty ,1)$ , which corresponds to coupling constant γ ∈ ( 0 , 2 ) $\gamma \in (0,2)$ . The critical case c_M = 1 ${\mathbf {c}}_{\mathrm{M}} = 1$ corresponds to γ = 2 $\gamma =2$ and the supercritical case c_M ∈ ( 1 , 25 ) ${\mathbf {c}}_{\mathrm{M}} \in (1,25)$ corresponds to γ ∈ C $\gamma \in \mathbb {C}$ with | γ | = 2 $|\gamma | = 2$ . Our metric is constructed as the limit of an approximation procedure called Liouville first passage percolation, which was previously shown to be tight for c_M ∈ [ 1 , 25 ) $\mathbf {c}_{\mathrm{M}} \in [1,25)$ by Ding and Gwynne (2020). In this paper, we show that the subsequential limit is uniquely characterized by a natural list of axioms. This extends the characterization of the LQG metric proven by Gwynne and Miller (2019) for c_M ∈ ( − ∞ , 1 ) $\mathbf {c}_{\mathrm{M}} \in (-\infty ,1)$ to the full parameter range c_M ∈ ( − ∞ , 25 ) $\mathbf {c}_{\mathrm{M}} \in (-\infty ,25)$ . Our argument is substantially different from the proof of the characterization of the LQG metric for c_M ∈ ( − ∞ , 1 ) $\mathbf {c}_{\mathrm{M}} \in (-\infty ,1)$ . In particular, the core part of the argument is simpler and does not use confluence of geodesics.
