Konoka is a cheerful and caring girl who lives with Asuna Kagurazaka and Negi Springfield. If anything, she is the mediator of the group, being both Asuna's best friend and Negi's biggest supporter. She appears to be the "mother" of the trio in the living facility, choosing to help, cook and look after Negi while putting up with the harsh comments Asuna made towards the child teacher. Yet even with her slightly oblivious mind, Konoka is one of the smarter students in the class (compared to her "Baka Ranger" roommate) though she doesn't choose to show it like other book-smart students outside an occasional membership in the "Library Exploration Club" with Nodoka, Yue & Haruna. A fan of fortune-telling, she has tremendous magical potential, having come from a family of powerful mages. Her father, Eishun Konoe, is the chief of the Kansai Magic Association, who married her mother, the school headmaster's daughter, in an arranged marriage in order to ease tension between the Kansai and Kantō (where Mahora Academy is located) Magic Associations. Her grandfather, Konoemon Konoe, is the dean of Mahora Academy and also knows of the potential of Konoka, both as a bride and as a mage. Occasionally, he attempts to try to broker a powerful marriage between Konoka and a male mage as an omiai (Japanese arranged marriage) for her. Konoka usually just bears through her grandfather's good intentions and tries to just pass it along as best as she can.
Outside Negi and Asuna, Konoka's closest relationship at Mahora Academy is with her classmate and guardian Setsuna Sakurazaki. Ever since childhood in Kyoto, the two had a close friendship, playing and protecting one another from their difficulties. One day, Setsuna failed to save Konoka from falling into a local stream. Blaming herself for the accident, she chose to avoid her friend at all cost. Even at Mahora, she still felt guilt ridden of previous associations and continued to remain distant, despite her friend wanting to restore their previous relationship. After the incident at the Kyoto trip, Setsuna's distancing ended; and the two became close friends once again. At the same time, Setsuna avoided any further feelings, associated with the various arranged marriages Konoka tried desperately to avoid.
She is a member of the Konoe family of the Fujiwara clan, the source for all imperial brides from the 8th through 19th centuries. Konoka was not informed by her father of her magical potential or of her family's mystic history, as he wanted her to live a normal life. Before learning of Negi's magical background, she was very interested (and still is) in fortune-telling and anything pertaining to the occult. She is the President of Mahora's Fortune-Telling Club.
Because of her magical background and her place connected with both Negi's stay and to the group his father formerly lead, Konoka eventually finds her way into the story as the "healer" of his own developing group. Although remaining oblivious and cheerful with her new position in the story, she is forced with greater responsibilities with her own awakening magical potential. Similarly planned and explored is her relation with Setsuna, established even before their part in the story as the only two members of the class from Kyoto and thus drawing on each other for the character development as master and guardian. Yet even with the growing threat and troubles, Konoka remains with her sweet, happy-go-lucky personality who believes everything will be all right in the end.
After his encounters with Evangeline, Negi gets a clue on the search of his father in Kyoto. Yet from his word of going to Kyoto, he also learned of Konoka's association with the Kansai Magic Association and is asked to protect her on their journey there. Yet for Chamo, Negi's perverted ermine partner, he saw this as a chance to make Konoka become a Pactio partner and get more "Ermine Dollars" in the process. Seducing Konoka with the Pactio already made with Asuna, she finally attempted to kiss Negi on the cheek...leading to a Botched Card and caused the magic in her blood to awaken. Negi and Konoka further bonded prior to Kyoto on a shopping trip for Asuna, but this is nearly ruined by the influence of the 3-A cheerleaders (under Ayaka's command).
Once in Kyoto, Konoka finds herself a massive target for several supernatural warriors, hoping to use her for their own devices. With her in danger, Negi, along with Asuna and Setsuna, are forced to fight back against the invaders while protecting Konoka from capture. However, one of these encounters forces the Kyoto-raised girl to release her dormant magical abilities unexpectedly to save Setsuna from a possibly disabling attack. With Konoka's powers finally revealed, the evil mages take her captive and use her to awaken a powerful demon, forcing Negi's squadron to come to her rescue and even forcing Evangeline to come to Kyoto to stop the menace. Ultimately, at the end of the battle, Konoka herself becomes a hero by kissing Negi directly on the lips, using her dormant healing skills to save Negi from petrification and likewise making her become Negi's fourth Pactio partner.
Konoka's magic ability first manifested on the tip of her finger during a shopping trip with Negi, and was briefly released when she healed Setsuna's arrow wound during a fight in Kyoto. When Negi was caught in the effect of a petrification spell, Konoka formed a full temporary pactio with him in order to reverse the petrification. The pactio process had also reversed the petrification spell on those affected at her home at the same time. Her artifact is an Onmyouji's outfit with fans that allow her to heal any injury within three minutes. She is beginning to learn magic from Negi and Evangeline, and is able to cast a few simple spells like Yue. She has strong affection for Setsuna, and this often makes their friendship seem more akin to a romantic relationship (although this mostly is from Setsuna's side, as Konoka has admitted in Volume 2 that she isn't ready for any serious relationship with anybody), and has occasionally shown interest in Negi Springfield (especially when he was magically altered by the Age-Deceiving Pills). She is sometimes shown in the manga dressed similar to white mages from the Final Fantasy series.
During the Wilhelm incident, Konoka was one of many girls who were initially kidnapped by Wilhelm and the Slime sisters, only for them to escape and assist Negi in the battle, with her rescuing Setsuna from the watery cell that she was being held in.
During the Mahora Festival, she along with Negi and some of the other girls had become trapped in the future where Chao had succeeded in revealing magic to the world. After a series of battles and narrow escapes, the group had returned to the past to stop Chao's plan. During the "Mage vs. Martian" battle, she worked in the infirmary, using her powers openly to heal those who manage to get injured in the mostly bloodless fighting.
Recently, she and Setsuna were invited to join Negi in his trip to Wales. She and Setsuna were practicing magic in Eva's resort, in which Konoka reveals a variation of her Pactio Healing outfit. She is also showing promise during a telekinesis exercise when she starts knocking down targets with psychic waves with relative ease. She is also a target for the Badge Collection game, but Yuna and other Athletic club members consider her as difficult with Setsuna always protecting her. Her badge is never targeted.
At present, she and the rest of the White Wing are enjoying the hospitality of Nekane's home and touring Negi's hometown. After seeing the petrified statues of the victims of Negi's village, Konoka becomes even more determined to master healing magic. Currently, she and the rest of the White Wing club had just passed through the portal into the Magic World. Konoka is ecstatic at the prospect of seeing fairies and other mystical creatures and places, though her mood immediately changes to extreme horror when Negi is severely injured by Fate and her Pactio Card sealed away, thereby preventing her from using her healing ability. However, as Asuna releases the White Wing's weapons and magical artifacts from their container, Konoka was able to heal Negi in time. However even with Negi back in the fight he could not stop Fate from destroying the magical gateway. This is turn caused a massive explosion of displacement magic that scattered Konoka and the rest of the White Wing members across the magical world. She has been journeying with Kaede, helping her out as a bounty hunter, and has recently been reunited with Asuna and Setsuna. Currently, the group have made their way to the festival and fighting tournament at Ostia. Despite being warned to keep a low profile due to the bounties on their heads, Konoka becomes excited at the various sights and events at the festival.
She then with everyone else goes to rescue Nodoka from the "Black Hounds", though she herself didn't play a part in the short-lived battle. Currently, she is back in Ostia, with her, Raken, and Chamo being confronted by two of Fate's Ministra Magi.
Although she remains the granddaugther of the Mahora dean, Konoka's magic and potential is not as emphasized. Instead, the second anime focuses more on her airheaded personality and her shoujo-ai relationship with Setsuna. In many scenes, Konoka appears to be more forward towards Setsuna, who ends up taking her comments or ideas to a different perspective, yet Konoka appears more oblivious towards the feelings.
Although she is a major member of Negi's team and an early Pactio in this series (she becomes the third Pactio), none of her abilities are connected in any way to her massive healing potential like in the manga or the first anime. Her Armor card involves a set of I Ching sticks (used for fortune telling) which she can manipulate like a whip, her Cosplay card lets her manipulate water with paper fans, and her Suka card turns her into a koala.
During the tug-of-war between Asuna and Ayaka using clothespins, Konoka is the one who reminds Negi of Ayaka and Asuna's relationship, implying that she is in the same class as the two since grade school.
During a number of scenes in the anime series, Konoka is drawn with a facial expression that resembles Ichijo from Pani Poni Dash!, which is one of numerous parodies in Negima!? as Pani Poni Dash was also produced by Shaft under director Akiyuki Shinbo and both characters were voiced by Ai Nonaka.
