Nekane Springfield
Negi's older sister. Her gentle personality is largely based on interpretations through disjointed flashbacks, so it is hard to identify precisely what she is like. What has been indicated however is that Negi's sister took on more of a motherly role in his life. As a side note, Asuna and Negi's sister feel similar for Negi. Nekane may not be the daughter of Nagi Springfield because when he was officially announced dead, he was 25, which doesn't make sense since she was still a teenager during and after his death, she may be Nagi sister or a relative of his, but if she is Nagi daughter, the only clear explanation is that Nagi married at an early age or she is his adopted daughter. 6 years ago, when demons attack the village where she and Negi use to lived, she was almost turned to stone trying to protect Negi from a petrification spell but was saved by The Thousand Master. (It is unknown if she knows she was saved by him.)
