ONA
Description
Ran Kogami, who operates under the kaiju alias Eleking, is a recurring character who works as an investigator for the organization known as GIRLS. She inherited the soul of the kaiju Eleking and serves in the investigation division, a role she chose specifically because it allows her to travel frequently. Her given name, Ran, is derived from the Japanese spelling of the English word lightning, which reflects her electric-based powers.

In terms of personality, Kogami presents a cool and serious exterior, a demeanor that has been described as deadpan. Despite this composed front, she has a number of personal hobbies, including watching anime, reading manga, and spending time on her smartphone. She shares a particular interest in yaoi fandom with another character, Reika, but unlike her, Kogami makes little effort to conceal this interest from the public. Her interactions with colleagues are generally straightforward, and she is known to be called Ele-ele by the character Tomomi.

Kogami's role in the story primarily involves her duties within GIRLS, where she is a more experienced figure. During the second season, she takes on a mentorship role, regularly training two new recruits, Yuka and You, in segments that appear across most episodes. Her initial encounter with the main capsule girl trio occurs when they are handing out flyers, introducing her as a mysterious new kaiju girl who becomes involved with their activities.

Regarding her relationships, her most defined connection is as a senior instructor to the newer members of GIRLS, though her cool personality suggests she maintains a professional rather than overtly friendly rapport. She also has a notable, if understated, relationship with Commander Black, as demonstrated when Commander Black accidentally steps on Kogami's whip and is electrocuted, revealing a key detail about her abilities.

The character displays subtle development through her increased role from a mysterious figure to a dependable mentor. While her core personality remains the cool and serious type, her function within the narrative evolves as she takes on the responsibility of training the next generation of kaiju girls, showing a different facet of her character beyond her investigative work.

Kogami's most notable ability in her kaiju girl form is her use of a whip that resembles Eleking's tail, which she typically keeps attached to her back when not in use. While it was initially believed that she could conduct electricity through the whip at will, it was later revealed that the whip is capable of generating its own electricity autonomously. This unique weapon allows her to channel the classic powers of the original Eleking kaiju, including the capacity to discharge high voltage electricity, in a compact and portable form.
