@Daisuke:
Well, from what I hear Chao sometimes spars with Ku Fei from time to time so she might also be a martial arts expert…
That's actually interesting to know.
@Daisuke:
Though it will be difficult to track her down in the third day, I mean her plan was so well organized. From recruiting Kazumi in volume 10, Hakase, a tech expert in her side, and a device whereyou can travel in time, it will be such a challenge. Plus some call her a genius for the fact, she's good at lots of things and she has the TOP test scores in Negi's class.
I thought her dialogue (before time jumping) a couple chapters ago implied she would be seen again by the characters on the third day. I mean, remember when she said "We should recruit Negi" or something along those lines? She did, technically…by giving him the Cassioppea, he was able to occupy the attention of virtually his whole class while Chao initiated her plans. What better way to finish an arc without the central antagonstic presence giving a lengthy dissertation upon the nature of her motives?
@Daisuke:
Though when she said, "relative" I'm thinking half sister or a close cousin. Not sure but who knows.
I ruled that out when I heard Nekane Springfield was Negi's cousin, rather than sister. Such makes sense because Nagi was in his twenties when Nekane was a teen, so their age difference cannot be huge. Furthermore, for a "lone wolf" mage who apparently hasn't forged a single practio card with anyone (even Negi's mother), I don't see Nagi as the type to go flirting with people. Chamo's "Thousand Practio Card" boast is almost certainly a lie; in my own view, Negi's personal charisma is all his own, not derivative of his Welsh background or distinguished heritage.
Furthermore, when Akamatsu introduced Mei (Naru's sister) in Love Hina, he never specified that her last name was Narusegawa, and since Mei reappeared in Negima with a different surname, it's possible that she's a step-sister and not a half-sister. Chao claims to be blood related to Negi, though.
Meh, maybe I'm just predisposed against the half-sibling issue. I guess I just don't see a comedic, light-hearted manga like this having "serious" themes outside of young romance.
