Yuu begging for his dad to wake up over and over, the doctors try there best to look away from what just happened. Yuu shouting at the top of his voice saying "I THOUGHT YOU SAID YOU WILL BE THERE, WHILE YOU SEE ME BECOME A BLACK KNIGHT, SURPASSING YOU!" As the doctors try there best to help Yuu's mental state. Yuu's power sent them all flying back. About to lose control again, Yuu heard his dad's voice from the inside of his head saying "I'm here for you". Taking a deep breath in and out, while tears go down his face, Yuu hugged his dad tightly like he wanted to crush him to death. While Yuu's dad opened his eyes smiling at his son, Yuu could have never wished for a birthday present as good as this one.
As the doctors gave Yuu's dad the money that he needs to pay the bills, he felt like he wished he was dead already. Pretending to act dead, it had no effect on the doctor.
Later on, Yuu started to have a better understanding of controlling his power when awakening Yin for the first time. Creating a limit when using his power and his form that he revealed again, in the tournament, he decided to name it "Dark matter". Making it so that he is capable of using his form whenever he wants and limiting his power so that he can use only 50% of his power, Yuu finally felt ready to head to school again after his mum and ad celebrated his birthday.
When heading to school, Yuu realized from the letter they sent him, that he was trapped in the lowest ranks in the school. There are 4 ranks in his school. The first one is Rank A, people that not only have full control over there power but has mastered the use of Yung so that their body is able to use Yin. Another thing you need to enter rank A is to have high magic power and made your own form of magic or ability. The second rank is Rank B, people that do have Yin but hasn't developed fully, so is not able to have their owned form of magic or ability. Then there is Rank C, people that can limit the destruction of there power but hasn't got to the point of using Yin. And lastly, Rank E, people that have no control or mastery over there power and can't limit the use of there power, which is the rank Yuu is stuck in now.
Yuu opening the door seeing a bunch of students messing around, he notices that Diamond isn't in this rank, meaning that he must be a higher rank until he turned around. Yuu already full of energy to have a rematch, Diamond didn't feel the same way, towards the person he already defeated. When Diamond gave Yuu the cold shoulder. The teacher arrives, Looking so unprepared and unorganized, the teacher walked in with his eyes closed, moving like he was drunk.
Everyone couldn't take the teacher seriously so decided to mess around and start using their magic in the class ground, knowing they're not allowed to do that unless the teacher says so.
Once the teacher opened his eyes, he kept the whole class frozen in the same spot. Showing who was superior here, everyone decided to get back in there sit and started to pay full attention to the class teacher.
While the teacher turned around to write his name down on the board behind him, one student was feeling brave so decided to teleport behind him, but before he could try anything, the teacher instantly turned around and kicked his head like he was a football, across the classroom, against the wall and shouted "DETENTION!".
Making the student realises he is no joke, he showed his destructive aura and lead the classroom to shake, looking at all of us, he wanted to get the message across that if we were to try anything silly in his own time, he wouldn't hesitate to treat you like a football and gave us a bonus with a detention.
Asking the student to come with him to the gym hall the class, the teacher wanted to see where the class level of skills and power is at, so decided to make the whole class fight him at once. While Yuu was heading to the gym hall, he took this as an opportunity of a lifetime to show the teacher what he is made of, so that he can move up a rank and make it to the top tier. But will Yuu's idea end up how he wanted it to end up as?
