Mei Sakura

Mei Sakura (佐倉愛衣, Sakura Mei) is kohai to her senpai, Takane whom she refers to as 'onee-sama'. She is deemed as a skilled Ministra Magi whose artifact is a broomstick. Mei is also a transfer student, sent to study from a North American mage academy before the Mahora Festival Arc. She is a 2nd year middle school student in Mahora Academy, making her a year younger than most of the 3-A student.

Mahora Festival arc
On the night before the festival, Mei, Takane and Gandolfini made up the group that arrested Chao, but released her on behalf of Negi. During the first day of the festival, she and Takane, realizing that Nodoka was at a high risk of doing something that would activate the World Tree's magic, tried to intervene during her date with Negi. Unfortunately, Negi came to Nodoka's aide, and as a result, Nodoka ended up trigger the World Tree's magic to turn Negi in a "Kiss Terminator" obsessed with giving her a deep kiss. When Mei and Takane tried to subdue Negi, he ended up giving them the first of many strippings.

On the second day of the festival, she took part in the Mahora Tournament, where she was swiftly defeated in one hit by Kotarou. Later on, after Takane and Asuna were also eliminated from the tournament, she and the other two noticed Misora and Cocone sneaking around and, upon realizing that they're there to investigate on Chao's plan, joined them in exploring the underground of Mahora.

In the timeline where Chao was successful in revealing magic to the public, the press constantly hounded Mei in the aftermath. She, along with Megumi, assist Takane in their mission to arrest Negi's group when they try to find a way to rescue Negi and return to the third day of the festival. While Mei's artifact was able to nullify the abilities of some of Negi's Ministra Magi, Asuna's "magic cancel" ability and Ku Fei's martial arts training resulted in Mei's group getting defeated and stripped bare. After Mei's group comes to (and given the Library Club's tour blazers as cover for their body), Nodoka used her Pactio artifact on Mei to find out where Negi has been held, and Asuna comforts Mei by promising her that they will return the world back to normal.

After Negi and his returned to the third day of the festival, Mei was shown along with Takane entering in the battle against Chao's robot army.

Magical World arc
Just before Fate Averruncus and his friends destroyed the portal linking the magical world to the real world, Mei along with Takane, Misora and Cocone went to the magical world for vacation, trapping them there along with Ala Alba. During the upcoming of the Ostia Festival, she and her group learned about Ala Alba in the magical world when she watched a news report.

During the fight against Cosmo Entelecheia, Mei aided Ala Alba in rescuing Anya, Asuna and the world during Fate's attempt of rewriting the magical world. After the Mage of the Beginning﻿ was defeated, she along with everyone from Mahora went home safely.

Abilities
Mei seems to have an elemental magic affinity for fire and is shown to be proficient enough to disarm Kaede and Setsuna at battle. Although in most fights, her true strengths were not demonstrated.

Pactio: Puella Genista (literally, "Broom Girl"): Her pactio artifact, the Favor Purgandi (Latin: Liking to Cleaning, Jap: Osōji Daisuki (お掃除大好き), "I love to clean" or "I love to sweep"), is a broom that she uses for combat as well as transportation, just as how Negi's does with his staff. It may be similar to the broom that Yue has. One possible power of the broom is to completely to disarm opponents with a stroke, but it is uncertain whether this is due to the broom, or Mei's own magical prowess.

Love Hina

 * Main Article: Mei Narusegawa

Trivia
In the final chapters of Love Hina, Naru mentions that she has a step-sister named "Mei", according to her Naru's mother married Mei's father. As she calls home to contact her mother, her step-sister picks up the phone instead. At the wedding of Naru and Keitaro, Mei shows up in small appearances and is the exact same appearance as the Mei of Negima. Due to her identical given name and appearance to Naru Narusegawa's step-sister from Love Hina, Akamatsu's previous work, many fans theorize that they are the same person. While Naru's sister Mei was first introduced in the Love Hina anime (where she had an entirely different personality) and thus was not created by Akamatsu, she was eventually mentioned in the manga, and made small appearances in the final chapter.

There are several points for and against the assumption:


 * Sakura's surname is different in both stories.However, since Sakura and Naru don't share a biological father and became stepsisters somewhat recently, Mei might simply be choosing to use her "original" surname.
 * Mei's hair is a reddish color in Negima, while the Mei in the Love Hina anime has hair is browner. However, several character's hair colors were notoriously inconsistent in adaptions of Negima (sometimes only later approved by Akamatsu) and none the depictions of Mei specifically in Love Hina are actually in color.
 * Mei appears in the Love Hina manga during Naru's wedding which took place in 2005 (two years after the events in Negima) but seems the wrong age. However, Tsuruko and Motoko appear during Setsuna's flashback on Kyoto trip. Naru and Seta also make a cameo appearance during Mei's pre-selection fight in Chao-bao-zi tournament . Dialogue and visual references to Aoyoma clan (such as Jack Rakan attempting a technique) and both Setsuna and Motoko using the Shinmeiryuu sword style suggest some kind of shared universe (compare to UQ Holder's status as an explicit sequel to Negima!).
 * Despite some other supernatural phenomenon appearing in Love Hina, actual mages do not. However, the Urashima clan uses ki-based techniques and their old inn seems to be the entrance of an old temple on a hill in Tokyo, which somewhat parallels the Kyoto magic association temple.
