"This...! How is this possible?" Baku's hand trembled from just stopping Haru's punch. He clearly remembered the difference in their powers from their previous battle, but what he was feeling now was completely different.
The huge gap that once stood between them had lessened, which was abnormal to him even after killing a thousand of Baku's hokō-sha.
What Baku didn't know was that Haru had an unique System – EX-Rank System, which didn't follow the regular standards.
'Quick! Engrave the Prana-circle of [Thermal Touch]...!' With his fist touching Baku's arm and him being shocked, Haru instantly started engraving his spell within a second.
"It won't work on me again, you brat!"
Quickly overcoming his shock, Baku, a thousand-year-old monster, instantly realized what Haru was doing.
