"You will learn more from your defeat. I never lost in my life though, ha-ha-ha." - elder Furinji, HSDK.
Also the thing abour learning three times as much from the defeat was drilled into me by chess master.
Nice but when you think about it... The fact that Yukina has such telegraphed moves, and that she has no idea what to do when they're being exploited, means that Touma kinda failed at teaching her how to fight...
@Askorti Exposing the telegraphs to someone other than himself who she'll be fighting often from now on will help her grow just as much as it helped this other girl, because when Yukina's fighting her father she already expects to lose anyway. You can only go so far teaching someone everything you know, eventually you have to teach them to learn on their own as well.
