(Good, simple descriptions. Nice work ^^)
"Alright, before we continue, I want to give a short lesson on elemental interactions. You already know that Raiton is strong against Earth, and weak against wind. In a fight, if you're being attacked with C-rank Raiton, you can use the element that's strong against it; wind, to counter. In order to cancel it out, meaning that the jutsus clash and stop each other, it would only need to be up to one rank lower. So D-rank wind techniques would stop it. Anything higher would continue onward towards your opponent."
"Now, if you were using C-rank Raiton against your opponent, you could destroy up to one rank higher of its weakness, Earth. So that would mean that if your opponent used a B-ranked Earth jutsu, a C-ranked Lightning would be enough to cancel it out."
"If elements are neutral against each other, say, wind and water, you would typically need to have the same rank in order to stop them. So, B-rank wind stops B-rank water and vice versa."
"However, if you use an element that's weak against your opponent's attack, it would need to be 2 ranks higher. So, back to the C-rank Raiton example. If you use C-rank Raiton against me, I would use A-rank Earth to stop it at the very least."
"I'll give you a short quiz... don't worry, nothing too difficult, I just want to test your understanding. Don't worry if you might get an answer wrong or not, just try your best. We are learning, after all."
Souji hands Alluka a piece of paper with some questions on it.

Souji hands Alluka a piece of paper with some questions on it.
1. I use a C-rank Earth jutsu against you. If you use its weakness to counter, what minimum rank would it have to be to cancel out the Earth? What happens if you use a stronger rank than that?
2. I use an A-rank wind jutsu against you. If you use a NEUTRAL element, what rank would it need to be to stop the technique? What elements are neutral against wind?
3. I use a B-rank Water jutsu against you. If you countered with FIRE, what would the rank need to be in order to stop it? What happens when Fire and Water interact with each other?
4. I use a B-rank fire against you. What rank does a water jutsu need to be to not only cancel out the jutsu, but continue towards me as an attack afterward?
