The conversation with Guozhi was enlightening, mainly because it gave Kaito hope of learning skills without relying on
At the end of Guozhi's explanation, he clarified for Kaito that because Kaito is a special student at the Kamigami Institute, he is entitled to free tuition for most lower-ranked skills, such as E or F Rank, but when it comes to A Rank Martial Arts, he only gets a small 10% discount.
Like everyone else, Kaito knows that the A Rank Martial Arts are very powerful and desirable, and therefore also very expensive. He can't afford them yet, but that hasn't discouraged him.
