Damage - With Luna, it's probably an instant-kill. Even without it, enemies will probably die from Flux.
Critical - He averages with 10%. You can bump that up to 42 with supports and Luna.
Speed: He averages with enough to usually hit twice against most enemies.
Dodge: It averages at 59 without supports or terrain bonuses, which is pretty good for a magic-user.

Rating: 10/10. No, your eyes do not decieve you. Canas deserves it. Even without stat boosting items, he is easily the best character in Rekka no Ken.
