Modern era

is a term used loosely to describe the time period from which Kagome Higurashi originates, 500 years in the future from Inuyasha's search for the Shikon Jewel during the Sengoku jidai. Kagome and Inuyasha are apparently the only people who can travel between the two worlds, which they do through the use of the Bone-Eater's Well. Kagome returns periodically from the past to play catch-up at school, but she eventually leaves it behind permanently to live with Inuyasha.

In Hanyō no Yashahime, a young Towa ends up in the modern era following the separation from her sister. She spends the next 10 years under the care of Kagome's family.
