Hasekura Reiri

Hasekura Reiri (支倉 冷理) is a student of Tokiwadai Middle School who appears in Toaru Kagaku no Railgun. She was the leader of one of Tokiwadai's three great cliques, one year before the main story.

Appearance
Hasekura has long brown hair, blue eyes and wears the Tokiwadai Middle School school uniform.

Background
At the start of Misaka Mikoto and Shokuhou Misaki's first year at Tokiwadai Middle School, Hasekura was in her third year and leader of one of Tokiwadai's 'big three' cliques. Her clique was the oldest of the three, but was in third place, with the other two having overtaken it (supposedly without intending to). It was described by one of its members as a carnivorous clique, with members willing to throw others under the bus to succeed.

Abilities
The exact nature of Hasekura's esper ability is currently unknown, but appears to involves the manipulation of liquid. As a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4.

During her game with Misaka Mikoto, shooting a ball-bearing against a target from a distance, she caused a liquid to swirl through the air around the tube she was holding and gather at the tip, causing a steam-like burst to shoot the ball-bearing on the tip forward. When ambushed by an unknown attacker, she used floating balls of liquid to block the initial immaterial bullets, and used a burst from her tube like a blade to slice the subsequent physical projectiles. The liquid balls are capable of detecting ultrasonic waves.

During their initial encounter, Shokuhou Misaki believed her to be capable of resisting her ability, with comments from Hasekura afterwards supporting the notion.
