NRPG Ninjutsu - Magical Techniques

[Pinky]

Earth doesn't really have a weakness against Fire. If the Earth and Fire jutsu are of equal strength then they both explode, which can be dangerous for either character. It's just that something has to happen, and if the Earth jutsu isn't affected then it would actually have an effective advantage against Fire.

The really "weak" element is Lightning, since most of the Lightning techniques shown in the manga have been melee while all the other elements have plenty of ranged attacks.
