Ashinoko
A Showa-era hot spring spirit and one of the seven newcomers to the spirit world. She and Goura have been tailing Miya and Hakone, trying to swipe their secret boxes—though how that's going depends on who you ask.
Her name comes straight from her hot spring's location in the Ashinoko district, one of Hakone's twenty hot springs. Pretty straightforward naming, honestly.
