Grandwell was given a sword by Rigel because he wanted to fight him fairly while he was using daggers. They did a warm-up fight since they wanted to recall how strong each other was.
"I only have half an hour left, so let's get started," Grandwell said as he readied his stance and stared at Rigel with his sharp eyes.
Rigel released sparks and immediately disappeared into thin air. Grandwell could see his movements like a flashing ball of light that moved around. He could see the pattern in less than a second and immediately dashed toward where Rigel was at.
Rigel expected Grandwell to be able to see him, and he began to clash his daggers with Grandwell's sword. The fight attracted Aria and Arnel who came to visit after they heard what had happened.
