Eventually, Iruma decides that he wants to raise his rank. Iruma is unable to answer the question so Opera explains that, with a high rank, it's still possible to travel to the human world.

Opera asks Iruma if he wishes to return to the human world. While they are shown to have a close relationship with Sullivan, they seem concerned over his decision to adopt a human grandson. They are often seen assisting Sullivan with his work, preparing Iruma for school, and taking care of chores. Opera is introduced as the competent servant of Lord Sullivan. Once the two met, Opera 'befriended' Kalego (and in extension, Balam) whom they often teased and bullied. At the time, Opera's description was somewhat similar to Kalego's (dark hair and ears and wearing both the girls' and boys' uniforms). Not much is known about Opera's life prior to their enrollment in Babyls Demon School, but Opera seems to have been employed or planning to become employed by Sullivan even then.ĭuring Opera's time at Babyls they were known as the Mysterious Top Dog of Babyls, popularly known (although identity-wise, not) to be very violent and brutal towards a second year and third-year students in the school. Their interactions with Naberius Kalego reveal that they have a somewhat more mischievous and sadistic side not normally shown in their professional behavior, which was especially prominent when they were students at Babyls. They are mostly reserved with their opinions, but will voice the occasional concern or cynical remark, and will sometimes dispense helpful advice. They often try to act as a voice of reason for Lord Sullivan but are usually ignored. Opera has a serious, down-to-earth personality most of the time, but they have a sense of humor and can be mischievous. In their high school years they wore the female uniform top paired with the male uniform bottom. Opera is androgynous in appearance, with delicate features, slight stature, and a plait but a masculine dress sense, and no otherwise overly feminine features.

They often wear formal attire, particularly a red vest over a white shirt and a striped red and white tie, and navy dress pants. They have red eyes, small thick black eyebrows, and a pale complexion. They have a pair of red, cat-like hairs protruding from their hair, in addition to the second, elf-like pointed ears they possess.

Opera has red hair with a straight cut fringe and a short plait.
