We searched for proton decay via p -> mu(+) K-0 Mton center dot years of data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection criteria were defined separately for K-S(0) and K-L(0) channels. No significant event excess has been observed. As a result of this analysis, which extends the previous search by an additional 0.2 Mton center dot years of exposure and uses an improved event reconstruction, we set a lower limit of 3.6 x 10(33) years on the proton lifetime.
