Kanna Skill Build

Unless you have enough damage to solo Horntail for experience, wouldn't it be better to just skip Koma Koma Sakura, Taima Ryuuseifu, and Kekkai Kikyou and just max Maple Warrior?

Taima Ryuuseifu could be useful if you want to try and dojo early.

Taima Ryuuseifu is also useful for any instance where you want to avoid getting stuck with Super Weapon/Magic Defense Up, Damage Reflect, and the like. Koma Koma Sakura is great for healing not only your self, but your party members. Kekkai Kikyou, assuming it works at all, is a great damage boost against any boss.

If you're not going to be bossing at all, sure, you can skip any of those if you want.
