CZ2128 Delta

CZ2128 Delta (シズ・デルタ / CZ2128・Δ) is an automaton battle maid and member of the "Pleiades Six Stars", the battle maid squad of the Great Tomb of Nazarick.

Appearance
CZ Delta is a short girl with red-gold straight long hair. She wears an eyepatch over her left eye, while her right eye has an emerald color and target-mark on the pupil. Her face is very delicate, it looks as if it was artificially crafted by hand. She wears accessories with military camouflage patterns. While her face is beautiful, she does not show her emotions and talks in a flat tone.

Her attire was similar to that of Narberal and Yuri. However, her biggest difference of those two were her urban camouflage accessories and the cute sticker attached to a corner of her skirt with ‘1 yen’ written on it. The other significant difference was the white gun she had holstered on her waist like how one would wear a sword.

Personality
CZ2128 Delta appears emotionless and has a silent nature. Her Karma is relatively high, which makes her, along with Yuri Alpha, one of the two "safe" Pleiades to humans. Though she usually ignores conversations from humans, sometimes there is a possibility to communicate with her. She hates cannibalism and likes cute things, such as Eclair Ecleir Eicler. She would often hug things she finds cute until someone of authority would tell her to let go.

Background
CZ2128 Delta was created as one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because she is unlikely able to stand against enemy players who managed to come this far, her only real purpose was to distract the invaders until the guild members of Ainz Ooal Gown are able to fully prepare for their final stand in the throne room.

CZ2128 Delta's creator was one of the Supreme Beings, other than Tabula Smaragdina, responsible for the design of Treasury's security systems. Thus, her character settings are set to be familiar with Nazarick’s mechanism unlocking methods.

It was only until Yuri told her that she was under orders from Ainz did she relent, allowing the Spear Needle to escape. Shizu explained since Eclair has been avoiding her, she came to the 6th Floor because it was full of cute animals which she could cuddle. To brighten her sister's mood, Yuri promised to tell Ainz who perhaps might give her a pet of her own.
