Well, Ouma did help Ikki spar(and I suppose out of good will) in volume 9. He basically just doesn't accept Ikki's philosophy. He believes that people who has more magical power are stronger, and to win with a weaker power is nothing but trickery. Ouma is actually trains even more insanely than Ikki though(but they're more power/endurance related).
