We show that by appealing to a Quark-Nova (QN) (the explosive transition of a neutron star (NS) to a quark star (QS)) occurring in a helium-high-mass X-ray binary (He-HMXB) system we can account for the lightcurve of the first superluminous SN, DES13S2cmm, discovered by the Dark-energy Survey. The NS's explosive conversion is triggered as a result of accretion during the He-HMXB's second common envelope (CE) phase. The dense, relativistic, QN ejecta in turn energizes the extended He-rich CE in an inside-out shock heating process. We find an excellent fit (reduced χ² of 1.09) to the bolometric light curve of SN DES13S2cmm including the late time emission, which we attribute to black hole accretion following the conversion of the QS to a black hole.
