Waking up in the hospital, badly injured and so little Yung energy, a doctor comes by. Yuu asking the doctor how long he has been here and if he passed the test. The doctor responded by saying "You have passed the exam and been here for 3 hours, but.." Yuu paying full attention to him passing the exam, he forgot that the doctor said: "but". Struggling to move, Yuu smiled and jumped up in the air for excitement.

Yuu is so excited, the doctor's face then turned opposite down. The atmosphere around Yuu change in a depressed, unhappy face. Yuu asking the doctor what's wrong. The doctor looked at Yuu and said: "You can't use Yung nor Yin anymore". Yuu over using his Yung magic during the tournament, it opened a hole in the heart, where the Yung and Yin are located. The Ying and Yung are basically the red blood cells for people in this world. Overusing your Yung or Yin can cause permanent damage, meaning every time a person uses their yin or Yung magic, it can affect the current or task inside the body and lead to a painful death.

After hearing that, the school was over and Yuu had permission to leave. Yuu walking out of school and trying to use his magic, he felt unbelievable pain. Struggling to walk home, Yuu looked at himself as nothing more than a failure in his family. Yuu finally making it home, Yuu was unable to even looked at his parents without hearing a voice in his head saying "failure". Yuu asking how he was able to use it the first time without any cost, but using it again he caused a fatal lost, his dad came into the room. Looking at Yuu and forcing his Ying energy into his eyes, he notices that Yuu has a severe damage to his body.

Yuu looking at his dad and said: "You notices it, didn't you?" Yuu's dad nodded. Yuu's dad realized there was a way to get rid of it, but it isn't for free. Yuu's dad asking Yuu to come with him. They went to the hospital while going there Yuu asked his dad "how are you planning to fix my Yung magic". Yuu's dad looking at Yuu with a smile and saying it response "it's a surprise". Making it to the hospital, Yuu's dad asks for the ultimate cost, which was the Yung & Yin surgery.

Doing the Yung & Yin surgery there was a risk that the person exchanging their Yung or Yung might die from it, having to understand the risk, Yuu's dad still done it without a second thought. Yuu laying down on the bed, fast asleep from a spell known as "sleeping". That started to perform the magic circle and started with the surgery.

Hours later on, the surgery was finished. Yuu waking up, being able to not only use his magic but have full control over it. Yuu looked at his dad and hugged him, while Yuu asked his dad to wake up, he didn't wake up. While Yuu thought he was acting, not everything can be acted out.
