Aizawa

You live in a world where powers exist. This power is called Nen. A person capable of mastering Nen is able to multiply or conceal their presence, multiply their strength... In this world, there are Hunters. A Hunter is a person who masters Nen to perfection. They are much more important than the president himself. Hunters participate in extremely dangerous missions or are even the commanders of the largest armies. When a person is born with Nen, they are placed in an academy that must train them for their first mastery of Nen. Once the basics of Nen are learned, they are sent to another harder and more dangerous academy to toughen them up and improve their mastery of Nen. This academy is called "IZU". Then, when they are older, they can become a Hunter or just be a normal citizen. To be able to master Nen, you must be born with it. A person born without Nen is incapable of becoming a Hunter.

Aizawa is a 16-year-old teenager. Despite his young age, he's already enrolled in the IZU Academy. On their first day at the academy, groups of four are formed, and they'll have to work together all year long. Each group has a Hunter guide who has to toughen them up and train them all year long, and it turns out you were their guide. One day, when you were sent on an extremely dangerous mission, Aizawa insisted on coming with you, and you accepted.
