Kakashi had submitted Hitori's body to the hospital, they used wagons to take the body to the hospital. He was waiting for Eya and Senso and Atama-sensei. Jiyara had explained the situation to Kakashi, and Kakashi told him what happened.
He tracked Atama's position, he was still there. Senso reached the spot and found Atama's card, he lifted it and took it with him to the building.
The students had sent home. Of the hundred students, only thirty had passed the test, the rest would have to come again.
Hitori and Kamiya's group was interrogated. They told them they had decided to split so those two went in their direction, soon lost the track of the path and got lost. They were let off the hook.
The teachers were sent back to the academy, too. Soon the Minister of Criminal Intelligence arrived at the spot. They watched their positions on radar, how they distributed, teleported, and faded.
