We report the first search for thedecay, which is forbidden by Lorentz invariance, using the data from 2016 to 2018 at the J-PARC KOTO experiment. With a single event sensitivity of, no candidate event was observed in the signal region. The upper limit on the branching fraction was set to beat the 90% confidence level.
