Elena Miyano

Since Elena has not appeared or interacted with other characters much on screen, much of her personality has been described by others. Elena seems to have been a very quiet person which has lead to people thinking she didn't understand much Japanese. However we know that she is fluent. Agasa seems to think that she is more suspicious than her "mad scientist" husband, Atsushi. Elena seems to have had a generally nice personality, which has earned her the nickname "Hell Angel" inside the Black Organization which implies her niceness on the backdrop of the criminal organization. Given the tapes she left behind, Elena seems to have loved her daughters. That said, Elena left her daughters at the mercy of the Black Organization even though she knew that she was going to "disappear" in advance.
