"Hey... you're that ninja."

Yeah, I'm hooked on Naruto. So the idea of converting it to BESM has crossed my mind about five thousand times by now.

But strangely, I have yet to do it. Well, until now, anyway.

The trick to Naruto is that it has a wonderfully well-developed "magic system" already. And rather than bend Naruto to BESM, I'd rather bend BESM to Naruto.

In BESM, you usually spend Energy Points to use certain attributes, like magic. This has a close parallel to "Chakra", the inner force ninja draw upon to power their various techniques in Naruto. The difference is that Chakra is not innate; instead, one converts one's own "stamina" into Chakra. And stamina can be said to be derived from one's physical health. But Energy Points are purely derived from Mind and Spirit.

So... eliminate Hit Points and Energy Points. Instead, Body x 10 gives us Stamina Points. However, we need to determine how well one can convert Stamina into Chakra. Mind seems to be shown as the strongest factor in doing so.

Essentially, if one's Mind is higher than both Body and Soul, one may convert Stamina Points into Chakra Points on a one for one basis. If one's Mind is only higher than Body or Soul, one may convert Stamina Points into Chakra Points on a four Stamina Points for three Chakra Points basis. If one's Mind is lower than both Body and Soul, one may convert Stamina Points into Chakra Points on a two Stamina Points for one Chakra Point basis.

One also has a maximum to the highest amount of Chakra they can produce equal to their Soul x 10. This is called one's Chakra Limit.

For a better guide as to how Chakra works in the series itself, see here.

I'll talk about the three types of ninja technique (taijutsu, ninjutsu, and genjutsu) in Naruto in the days to come.
