Terumi's world shattered as she witnessed Han's real power. For the sake of power, Terumi faced many hardships. One of the hardships that she had to face for the sake of becoming strong was a venture to the second floor. It was not an easy task. She and her group of HTC friends challenged the guardian of the 1st floor.
That was a very strong opponent that they faced. The guardian was so strong that while defeating it, they lost half the members of their team. Those who were lucky enough to survive struggled to live in the harsh and deadly environment of the second floor. After only 6 months with the exception of her, the whole team died. But after that when Terumi finally came back she was stronger than ever.
But when she saw Han, the elder of the ghost faction who had never kept a foot out of the 1st floor was stronger than her… That boiled her blood with anger. She became too enraged at herself. Why was he stronger than her?
