| Summary:
We present spectroscopic identification of 43 quasars and 11 candidate
obscured quasars in the epoch of reionization (EoR) at $5.71 le z le 7.02$,
along with 29 galaxies at similar redshifts. This is the 24th publication from
the Subaru High-$z$ Exploration of Low-Luminosity Quasars (SHELLQs) project,
which exploits the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP)
imaging survey to search for EoR quasars. The HSC-SSP survey has completed, and
this paper is likely the final installment of major (unobscured) quasar
discoveries from the SHELLQs project. In addition to the EoR objects, we
identified five strong [O III] line emitters at $z < 1$, 30 Galactic brown
dwarfs, and 14 passive galaxies at $z sim 2$, which contaminated our sample of
photometric quasar candidates. The present paper focuses on describing the
immediate outcome of the spectroscopic observations, while a statistical
analysis of the full SHELLQs sample will be presented in our next publication.
