[Brat, you do know you can't use your Spirit Master abilities or any soul-type abilities, right?] the senior said.
"I know, Senior. I won't use any," Klaus replied.
All around him, everyone was silent. In fact, the instructors present were also speechless after hearing Klaus's challenge.
They had just heard him declare a challenge against five of the most powerful factions in the inner section of the academy. Klaus had challenged them all to a 1-vs-3 battle.
"Are you insane, Klaus?" Lucy said, walking to his side. "Challenging the five top factions to a duel is the last thing you want. Let me tell you, there are powerful individuals here that even I wouldn't challenge them."
Lucy was visibly panicking. She may be a powerful Sage, but even there are Sages in the inner section of the academy she wouldn't dare challenge.
Klaus just challenged them all.
