Information about ghost and hunters

Yana talks to Leo on the phone and tells him:

Yana: Do you know what rankings are for ghosts and hunters?

Leo: I don't really know what this is about.

Yana: The ranks are C, B, A, S, SS, SSS and the grades consist of beginner, advanced, skilled and special grade, and the rating consists of 1 to 5 stars. I am of rank S skilled 3 stars along with 8 other students who were chosen by big 3 hunters they are called so because they are the only people who have SSS rank, special grades, 5 stars, the other students are promoted to A but if they have lower performances starting from B, the C rank is given only to students at the academy.

Leo: I see, I saw one of the big 3 hunters who fought Sokka and now Joester.

Yana: He is Edward is considered the strongest of the big 3 hunters, even Joester knew him before I knew him.

Leo: Whose team are you on?

Yana: Henry's team.

Leo: Mirai caught the Ghost Demon or Unseen Criminal, this ghost for 10 years omitted married couples.

Yana: Ghost Demon was SS, Mirai got a big reward from him.

Leo: I see and what powers do you have?

Yana: I haven't unlocked them yet !

Leo: Okay.

Yana: Big 3 hunters have special interesting powers.

Leo: Which ?

Yana: All the lyrical powers are interesting, all I know is Henry's powers, but I don't really know the others, Henry's powers consist of the first wave of absorbed energy which allows him to use his pistol based on ghostly energy, followed by the power that makes him able to shoot with the sword, another power is that it allows him to get out of the ground. thousands of 2-meter blades that make a ghost cut possible, and another power I know is that it allows them to absorb ghost powers with a certain amount of energy and use them for 1 minute.
