Domino

Domino (ドミノ) is a guard of Impel Down serving under Hannyabal.

Appearance
Dressed in the militaristic-style uniform of many of the staff, Domino is the most normal looking of the high-end officers of Impel Down as well as the most professional-seeming.

History
Domino first appeared to conduct a body search on Boa Hancock, who petrified her with the Mero Mero no Mi powers, so Monkey D. Luffy would not be detected. After that, Domino was turned back to normal and accompanied Boa Hancock to Chief Magellan's office in Level Four.

Two hours before Portgas D. Ace's execution, Domino appeared outside of Magellan's washroom to inform him to prepare for Ace's transfer to Marineford. She scolded Magellan for taking so much time in the washroom, and that it would be tainting their record if they were late.
