We completed the 2nd stage. I asked sensei why this paper turned into red. Sensei explained that this paper is made of a special kind of tree that can sense the presence of Sasis Energy and turn into red. Shizuka said we had to work very hard. Shin said it wasn't a big deal. But sensei said if this stage is not that hard then the last stage has to be very hard. I said though the last stage will be hard but we will complete it. Sensei told us to get ready for the last stage.

Sensei took us to a waterfall. Sensei said here we are going to complete the last stage or more specifically the Sasis training. Shizuku asked why we have to train here. But the sensei showed us an evil smile and said now you all have to sit under the waterfall for approximately 1 hour. Then I have more tasks for you. 

After a while, we 3 people were sitting down in the waterfall. The water was so cold. Few minutes later I asked sensei if we sat under the waterfall, we wouldn't catch a cold. Sensei smiled and said, "It's not your headache, think of yourself instead." Shin stood up from the waterfall and said if he tries to scare him like this, he won't accept it. Sensei scolded and said, "Can't you stay quiet like Shizuku?" But after a while, Shizuku fell unconscious and fell into the water. Then, we took Shizuku and she got back to normal. She then said where is she? Is She dead?. Sensei said she lost consciousness during the training.. If you all can't do this task then you can't use Sasis Energy anyway. This word hit us very hard. So, we got back to the waterfall and sat there quietly. Sensei said if you succeed, then none can stop you to be a reaper. 

No matter how painful the stages are, we tried our level best to be successful. I was thinking in my mind, our sensei must have gone through this harsh training. If others can do it, then we can also do it. After an hour, sensei told us to stop. We became very tired after this. Our heads and bodies were trembling. Sensei then said that's enough for today. We will spend the night here. 

The next day, we woke up and saw sensei brought 3 drums and plenty of wood. Sensei said, "Oh! You all woke up! Get ready after having breakfast because now you have a lot of training to do." After having breakfast we prepared ourselves. Sensei then explained that the training you are doing will manifest your Sasis Energy. After you complete all of the training, I will give a leaf that you 3 have to fly. If you can fly the leaf then you have fully awakened the Sasis Energy. In the end, I will teach you some techniques that can be used by Sasis Energy. So, now your first task is to sit under the waterfall's cold water for an hour and then there will be more. I want you to learn Sasis faster. 

After hearing this, we sat under the waterfall like yesterday. But it was less painful than before. After doing it for an hour, Shizuku said I didn't feel any pain during this training. I support it. Shin also said he didn't feel any pain. Sensei explained, "Because Sasis Energy reacts against it. If you think about it carefully, you will find out that your body is much stronger now. While doing this, your Sasis Energy comes out from every inch of your body and works as a shield. That's why you didn't feel any pain." Shizuku said if that's so, then we have learned how to use Sasis Energy? Sensei said it's not over yet. Now do 50 push-ups. Then I will arrange the other training sites. We did 50 push-ups and sensei called us and said now help me light the fire. 

We helped him. Then he told Shin and Shizuku to fill up the drums with water. Then sensei told us all to get into these drums for another hour. But the water is warm. I said, if we can endure cold water, then we can also endure the hot water. 

Then we went into the drums and sat there. It wasn't easy. Sensei said the temperature may reach 100c, so be careful. Shizuku spoke up, "We have endured many harsh training sessions in these 5 days. I will no longer do it. Today, we will finish this training." Everyone got excited. Seeing this mental development, sensei was surprised. Then we completed our training in the morning. Sensei now gave us leaves and asked if we are ready. We didn't say anything. Seeing our faces, sensei said, "Begin!"
