The Fearsome Well Spirit.

Kisume (キスメ) is a rather shy Tsurube-otoshi who usually spends her time in buckets. She is often seen in dark places such as caves or wells. As a midboss with no dialogue and a sparse official profile, little is known about her.

She debuted in Touhou 11: Subterranean Aminism as the Stage 1 midboss.
