From his name we can tell that he is male or at least that Nerona Imu from the void century was male considering he is referred to with the honorific 聖(Sei) and not 宮 (Gū) which has been used for other female Celestial Dragons like Saint Shalria, Charles’ sister. So unless Imu is different from the Nerona Imu of the void century Imu is definitely male.
The other interesting thing about his name is that the characters イム (Imu) put together become 仏, which means Buddha. Similarly the three katakana characters ネロナ (Nerona) put together becomes the word 神 kami, which means God.
