  "abstract": "With an aim of establishing how the [S/Fe] ratios behave at the very low metallicity regime down to [Fe/H] ~ -3, we conducted a non-LTE analysis of near-IR S ~ {\\sc i} triplet lines (multiplet 3) at 10455-10459 A for a dozen of very metal-poor stars (-3.2 <[Fe/H] < -1.9) based on the new observational data obtained with IRCS+AO188 of the Subaru Telescope. It turned out that the resulting [S/Fe] values are only moderately supersolar at [S/Fe] ~ +0.2-0.5 irrespective of the metallicity. While this \"flat\" tendency is consistent with the trend recently corroborated by Spite et al. (2011, A&A, 528, A9) based on the S I 9212/9228/9237 lines (multiplet 1), it disaffirms the possibility of conspicuously large [S/Fe] (up to ~+0.8) at [Fe/H] ~ -3 that we once suggested in our first report on the S abundances of disk/halo stars using S I 10455-10459 lines (Takeda & Takada-Hidai 2011, PASJ, 63, S537). Given these new observational facts, we withdraw our previous argument, since we consider that [S/Fe]'s of some most metal-poor objects were overestimated in that paper; the likely cause for this failure is also discussed.",
