Thunderzen's Conditions

John's expression remained neutral upon hearing this from Thunderzen as he did not care if the world knew who he was or not.

"With this in mind, going forward I must regretfully forbid you from using that unique ability of yours," Thunderzen continued, causing John's neutral expression to turn into a frown.

While Thunderzen did not specify which ability he was speaking of, both him and John knew he was mentioning using his Asura Transformation Art. It was the only battle art he used that had any sort of connection to the word Asura.

"May I ask why?" John asked while keeping his voice calm.
