Kadosaka Rina

Kadosaka Rina (角坂凛奈) is a student of Tokiwadai Middle School who appears in Toaru Kagaku no Railgun. She was a member of the Mikagami Clique, one year before the main story.

Appearance
She has light-colored hair and wears the Tokiwadai Middle School uniform.

Personality
While she and Sukezawa Sena like and seek the benefits of Mikagami Nagisa's ability, they are both loyal and care for her beyond that. After an outburst from her, they sought to make up for the stress they ended up putting on her.

Background
At some point in the past, Kadosaka and Sukezawa did Mikagami's hair up in her current ribbon.

First Year Arc
Around the time tensions were rising between the Mikagami and Hasekura cliques, with several skirmishes having occurred, Kadosaka and Sukezawa were with Mikagami, bringing up and offering sweets. As Mikagami was considering apologizing to the other clique to settle things, the two rejected that course of action as it would be the same as saying they were at fault for the initial incident, both vowing to protect her before asking for a few favors with her ability, though Mikagami had already started to leave. The two accompanied Mikagami, seemingly oblivious to her worries and internal dismay at how things had turned out.

Not long afterwards, as the three were walking together, they were attacked by Yasutoba Suika, who sought to crush the Mikagami clique's leader. After briefly getting away from the assailant, Mikagami urged the two to go a different way to her as she was the target, and ended up shouting to them as they refused, venting her feelings regarding her ability and the circumstances it had caused. After Mikagami left, hoping they would get to safety, the two lingered behind. Knowing the stress they and others had been putting Mikagami under, the two chose to stand in Yasutoba's way to make up for it. They were ultimately defeated, but remained defiant and refused Yasutoba's demand to call for Mikagami. However when Yasutoba moved to strike them, Mikagami returned to defend the two and began pushing her back. Yasutoba attempted to rattle Mikagami with comments regarding her clique, silencing the two when they tried to speak, but Mikagami was not rattled and proceeded to finish her off with a body slam.

Kadosaka and Sukezawa were present near Mikagami as she announced to her clique the temporary truce with Hasekura in light of a possible external culprit, and quietened objections from members with words and a promise for use her ability for each member if the culprit being caught.

When the Mikagami and Sha cliques reinforced the Hasekura clique in a raid on the headquarters of Montgolfier, the culprit behind the attacks that instigated and aggravated the clique conflict, Kadosaka was involved in the resulting battle with Montgolfier's operatives and their prototype weapons.

Abilities
Kadosaka is a Level 3 esper who can create a exoskeleton,  similar to that of shrimps and crabs. In theory, she can make an armor on par with a battleship's armor, though in practice she couldn't move with an armor that thick.
