  We consider an axion-like particle coupled to the Standard Model photons and
decaying invisibly at Belle II. We propose a new search in the
$e^+e^-+\text{invisible}$ channel that we compare against the standard
$\gamma+\text{invisible}$ channel. We find that the $e^+e^-+\text{invisible}$
channel has the potential to ameliorate the reach for the whole ALP mass range.
This search leverages dedicated kinematic variables which significantly
suppress the Standard Model background. We explore the implications of our
expected reach for Dark Matter freeze-out through ALP-mediated annihilations.
