Scene changes to an unknown city". Once there lived many humans. After the Cavles came here and started massacring people, they occupied it. Then reapers came and killed them. But at present many Cavles have been hiding here. To defeat the Cavles, many reapers were killed here. The whole city is destroyed and full of human skeletons. There is a bar where many Cavles are hiding. They are following a Cavle. It was eating human flesh. It looks mostly like a human but it has four arms and one tail. This Cavle said, I'm feeling very bored. I don't like eating this weak person's flesh again and again. Other Cavle told him, General ! there is nothing but weak (non-reaper) people to eat. But the General separated the other Cavle's head with his tail and killed him. He said, I want to eat reapers. I want their blood and flesh. It won't be long when our king will kill them all. 

On the other side, we were shocked to see sensei in this mood. He said, today I will teach you a defense technique. It's called Sasis Shield. I think it's the best technique for defense. Nanami said, but sensei, it's child's play to learn. Teach something big. Sensei replied, your Sasis isn't that great to teach you some big techniques. Sense then told us to release Sasis. We release the Sasis. Sensei then told us to shape it. We tried to shape it. But when we shape it a bit, it ruins. But we tried again and again. Shin couldn't shape it a bit. Sensei said it won't work if you just shape it, put more Sasis for a while after you make a shape of it. Hearing this, Nanami tried again. Shizuku was demonstrating carefully to shape it. Suddenly Nanami created the shield. Sensei tested the shield and congratulated Nanami as he had learned it. Nanami said it wasn't a big deal, sensei. I learned about Sasis control very early. We tried a lot but couldn't do it. Nanami said to us, "Sensei, they won't make it. If they even try it for continuous 10 days, they won't learn it." Seeing Nanami mocking us, Shizuku got depressed. Shin was bad mouthing him silently. I also felt depressed that he did it so fast but we couldn't.

Sensei told us this is useful for your first mission. Let me instruct you more. It's not that hard technique to learn. First you shape your Sasis into a hard shield. More specifically, firstly put your hand forward and draw the Sasis into your hands and just shape it. It's the shield. Nanami said it would take just 2 minutes for me to do it. Shizuku requested sensei to show us a demo. Sensei agreed. Sensei put his hands forward and was drawing Sasis into his hands. This Sasis was so intense that we could feel it. At that moment, he created a square shield and said if you want, you can touch or punch it. I touched it. Shizuku was trying to understand it. Nanami said, there are more powerful shield techniques than this, sensei. Shin punched hard but injured his hand. 

Sensei said, today you will make a shield like this. Am I clear? Shizuku asked if we can make it in any shape. Sensei said yes. He told us to train outside. It's not safe doing it inside the house. We all went outside. Sensei then started to train us. He told us, firstly take your position. Then draw your Sasis into your hands. But then he stopped because he saw us very tired. He gave us a break. We went inside the house. When I was going, a postman came and said he has a letter for me. I took it and then the postman left. This letter was from my aunt Jane. She said, "How are you, Noya? I heard you have become a reaper. Did you make any friends? You didn't say anything. Your father wanted you to be greater than him when you get older. And I have a thing to say but I will say it later. Take care of yourself."

 After reading it, I was highly motivated. Then I went outside and tried to learn the technique. Shizuku asked where Noya is. Sensei said he isn't here inside. Then they went outside and saw I'm training. Seeing my training, Shizuku was inspired and joined. Shin said , you will train now too? Then ok, I will go train now. Shin also joined. After a while, I created a shield. Shin and Shizuku also did it. Then sensei congratulated us and said, you 3 have managed to learn this technique. Now you will learn Healing Technique which is not an easy technique at all. He was talking in a serious tone.
