Lucky Seven Chōmei

Lucky Seven Chōmei (ラッキーセブン重明, Rakkī Sebun Chōmei), more commonly known as the Seven-Tails (七尾, Nanabi), is one of the nine tailed beasts. It was last sealed within Fū from Takigakure city in Izumo.

Appearance
Chōmei resembles a blue, armoured kabutomushi (カブトムシ, rhinoceros beetle), with six of its seven tails resembling green insect wings, along with the seventh tail, all growing from the end of its abdomen. The stem of the tail is green but the wings are orange. Its eyes seem to be covered by a helmet-like skull, from inside of which, an orange glow can be seen. It also has spike protrusions on its shoulders and a row of slits on each shoulder, and six legs — three on each side. The legs are also covered by the blue armour, with the exception of extreme ends which are green in colour. It has two pincers on its face, usually covering a mouth full of sharp teeth. On its back behind its head, it has a large two sectioned horned protrusion. During the last remaining days of the Sage of the Six Paths, Chōmei was just in its larval stage of development but still had its tails.
