Kotatsu-neko

In a previous life, this wandering cat perished in the bitter cold of the Edo period, and its intense longing for the warmth of a kotatsu transformed it into a massive cat spirit. Quiet by nature and thoroughly laid-back, it frequently appears at the Moroboshi household or sits alongside the school principal over tea and taiyaki. Beneath its seemingly gentle demeanor lies astonishing physical power and sumo technique capable of sending powerful foes flying, making it one of the series' most formidable hidden powerhouses.
