Dean listened to his student, who had a basic understanding of the element. However, Dean would add some information, even if it was just for trivia sake, he always enjoyed adding more.
"Not bad, Chojuro. Nonetheless, Fire is a very powerful element and requires quite some courage to master. The element comes forth in form of streams, projectiles of Fire, condensed forms and even ash. The canon list in itself isn't that spectacular, but with some skill, you'll be able to use Fire effectively in battle. Some Fire techniques are released through the mouth, others are materialized through the ground to erupt from beneath the opponent, and others are simply fired from the hands. As you said, Fire is weak to Water due to it smothering it and its strong to Wind because the Fire is simply enhanced by the Wind. This allows you to use it in combinations, by first using a Wind technique, and then shooting a blast of Fire, to make a strong fire technique. Or use it against a Wind blast of the opponent, to cause the Fire to go towards them. That's elemental interaction right there, I believe some previous teachers of yours had probably covered that as well.
Nonetheless, we'll be going through Fire with ease, but first, we must make sure you are compatible."
Dean reaches into his bag, where he retrieves a small white paper and hands it to Chojuro.
"That's chakra paper. Now, I want you to channel your chakra into the paper, and form it into Fire based chakra. You have to imagine Fire, its properties, its heat, its destructive abilities. Feel it, and manipulate it. If successful, the paper will burn and form into ash. Sit and meditate whilst you do this, and explain it in detail."
Dean waits for his student to do as he asked.
