His alias, the Black Magician, had become quite tiresome even in the game.
"The opponent is the Black Magician."
"I heard you defeated the Black Magician once. Give up; no one can rival the Black Magician's power."
All the characters from the game were familiar with that nickname. At the time, it had seemed like he had built up quite a reputation.
However, that nickname had a clear origin. The mysterious figure who had attacked the Grand Prix circus in the past.
Bouvalle briefly mentioned the name and didn't bring it up again. It wasn't appropriate to talk about an elusive criminal during a opening ceremony.
The atmosphere definitely changed once that name was mentioned. The acrobats sitting on the terrace looked different, their eyes filled with fear, sadness, and hatred alternating on their faces.
Bouvalle must have sensed the change in atmosphere, as he quickly moved on to the next stage after the opening ceremony ended.
