Relativistic outflows with neutrons lead to hadronuclear reactions, and resulting subphotospheric gamma rays may explain prompt emission of gamma-ray bursts. In this scenario, quasi-thermal neutrinos in the 10-100 GeV range should be generated, and they may even have a high-energy tail formed by neutron-proton conversion or shock acceleration mechanisms. We demonstrate the importance of dedicated searches with DeepCore+IceCube, though such analyses have not been performed. Detections allow us to see roles of relativistic neutrons as well as effects of cosmic-ray acceleration.
