Mibuki Kazan

The Glasses Clique Girl is an unnamed student of Tokiwadai Middle School, currently a member of Shokuhou Misaki's clique and formerly a member of Hasekura Reiri's clique, prominent in both.

Appearance
The girl has long straight black hair and wears oval-rimmed glasses. As a Tokiwadai student, she wears the school's uniform.

Background
The girl's background is largely unknown, but she was in Hasekura Reiri's clique during Misaka Mikoto and Shokuhou Misaki's first-year at Tokiwadai, and would later join Shokuhou Misaki's clique.

Daihasei Festival Arc
Around the time the Daihaseisai planning committee were trying to get the Level 5s for the opening ceremony, the girl was present with Shokuhou Misaki, Hokaze Junko, Asato Kisa and other clique members at a café when the topic was brought up. When Keitz Nokleben made his presence known, the girl stood up but was stopped by Shokuhou's Mental Out and sent away along with the others, the encounter to be forgotten.

On the second day of the Daihaseisai, she was among the members of Shokuhou's clique who were tasked with taking care of Misaka Mikoto, keeping her occupied and restricting her movements,  while Shokuhou was away dealing with the situations regarding Misaka 10032 and Kihara Gensei.

First Year Arc
The glasses-wearing girl was with Hasekura Reiri, along with Asato Kisa, when she ran into Mikoto and the other two top clique heads in a hallway junction. When Hasekura returned after taking the Level 5 away for a brief contest, she asked how it went and on Hasekura saying she lost, the unsure girl told her that a clique leader should not say that out loud like that. She and Asato then discussed the situation regarding the clique and the two Level 5s.

When Hasekura Reiri first encountered Shokuhou Misaki, the glasses-wearing girl was accompanying her, together with Asato. When Hokaze Junko tried to impede Hasekura's attempt at engaging Shokuhou in conversation, the girl started a fight with her, which the two continued elsewhere while Hasekura talked with Shokuhou. The two became quite enthusiastic in their battle, which was eventually ended inconclusively by Shokuhou's Mental Out after Hasekura and Asato had finished their respective conversations with her, with the two made to awkwardly walk off in opposite directions.

Astral Buddy Arc
The glasses girl was present at a clique meeting, during which Hokaze was drawing a picture of the ghost following her and an exhausted Shokuhou came in after having her bag stolen by a lemur, with the girl participating in the clique's retrieval operation afterwards, as part of the group's Wasp Unit.

When Shokuhou was incapacitated and kidnapped by Yumiya Iruka and Houjou Arei, the girl, Kobayashi Satori and several other clique members were attacked en route and prevented from coming to their queen's aid in time.

Abilities
Her esper ability is currently unknown, but as a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4.

She is proficient in hand-to-hand combat, being able to match a second-year Hokaze Junko during her time in Hasekura Reiri's clique.

Trivia

 * In the last episode of Toaru Kagaku no Railgun S, she seems to appear in Shokuhou's cameo alongside Hokaze Junko, Asato Kisa and another clique member, however in that case, she and Asato have different hair colors/shades than in other media, such as the colored manga-related illustrations (such as on the cover of Volume 11) and the character designs for Toaru Kagaku no Railgun T.
 * Episode credits refer to her using the term (食蜂派閥), which can be translated as "Shokuhou Clique", instead of her name.
 * After the airing of, Ogino Kentarou confirmed the voices for the unnamed members of the Shokuhou clique. Ogino referred to this girl by 'straight long glasses-san' (ストレートロングの眼鏡さん).
