Jack the Ripper

Jack the Ripper (ジャック・ザ・リッパー) is a mid-tier undead being that Ainz Ooal Gown summoned during the E-Rantel Cemetery Incident on saving Nfirea Bareare.

Appearance
It has green hair that grows upwards like the pattern of a flame and long angular elf-like ears. Its face is cover completely by a white smiling mask with yellow eye holes in the shape of four-pointed stars and is dressed in a black overcoat with purple outlines and white buttons. The tip of its fingers are all covered with sharp blades.

Abilities
As a mid-tier level undead, it easily overwhelms its low-tiered skeleton opponents. It has a very thin body frame and seem to lack muscles, but it makes up for it with its lightning speed agile movements and deadly precision attacks. It laughs hysterically as it fights. Its slashes are so fast that it leave a slight afterimage.
