I guess it can be said that Opera is a girl...though its not even sure because Opera wears both like Kalego who is wearing a skirt at the time it wasn't even preferable so... ╮(￣▽￣)╭
Wasn't Opera-san NB? They wear female top and male bottom uniforms.
Yeah this is a closer explanation of what Opera-san is. Opera-san just probably wore a female top since its comfortable or Opera's family is somewhere like that.
Opera san was a girl!!!??! Thought she was boy lol
