Tongue Demon

None

He fights primarily with his elongated tongue, sharp and strong enough to slice through solid objects, alongside considerable raw physical strength typical of the mansion's demons, before being defeated during the Tsuzumi Mansion Arc.

The Tongue Demon is a muscular, gray-skinned man with dark blue hair swept back to reveal two small horns, two sets of eyes, and an extraordinarily long, blade-sharp tongue.

The Tongue Demon is territorial and vicious, treating the Tsuzumi Mansion as his private hunting ground and attacking any intruder without hesitation.
