We report the discovery of 28 quasars and 7 luminous galaxies at 5.7 $\le$ z$\le$ 7.0. This is the tenth in a series of papers from the Subaru High-zExploration of Low-Luminosity Quasars (SHELLQs) project, which exploits thedeep multi-band imaging data produced by the Hyper Suprime-Cam (HSC) SubaruStrategic Program survey. The total number of spectroscopically identifiedobjects in SHELLQs has now grown to 93 high-z quasars, 31 high-z luminousgalaxies, 16 [O III] emitters at z ~ 0.8, and 65 Galactic cool dwarfs (low-massstars and brown dwarfs). These objects were found over 900 deg2, surveyed byHSC between 2014 March and 2018 January. The full quasar sample includes 18objects with very strong and narrow Ly alpha emission, whose stacked spectrumis clearly different from that of other quasars or galaxies. While the stackedspectrum shows N V 1240 emission and resembles that of lower-z narrow-linequasars, the small Ly alpha width may suggest a significant contribution fromthe host galaxies. Thus these objects may be composites of quasars andstar-forming galaxies.
