toriel need to use a manual to figure out how to raise kris for most of his childhood, i would not be surprised if she just thinks kris doesn't have a defined sex
kris also has jack shit on his side of the room and only wears asriels hand me downs, based on the wardrobe in the dark world toriel never bought clothes for him either
as for periods and bras, again toriel never bought kris clothes and the sweaters are probably large enough to hide kris' figure pretty well, and kris is known to not show up to school according to alphys in ch1, could easily skip a day or two each month due to cramping
