The next morning, Rose was feeling well enough that she was up to some training with Ryūji.
"Alright you two, this training is to help your engagement power, Blade of the Flame Dragon," said Gakushu as they stood inside a stadium.
"Are you sure this won't hurt Rose?" asked Ryūji with a worried expression.
"Actually, this will help her even more, after a dragon fights off an illness their energy spikes, and Rose is too young to let that energy out in the amount she needs," said Gakushu.
"Alright, so what do we do?" asked Ryūji.
"The power of engagement is linked to your emotions, think of an emotion that you share and use it as the base," said Gakushu.
"That's an easy one," said both of them as their hands started to glow.
"Blade of the Flame Dragon," said Ryūji as he swung Slash Breath, which created a flaming dragon that destroyed a dummy several feet away.
"Whoa, that was a strong attack," said a ten-year-old boy who had been hiding in the stands behind them.
"You're Aspen, King Dunkon and Queen Emerald's son," said Gakushu.
"Sorry about hiding like this, I just wanted to see what a Dragon Crisis could do," said Aspen as he jumped off the wall that seperated the stands from the arena.
"Then you should have just asked," said Ryūji with a smile. He then noticed the green stone in the necklace that Aspen was wearing.
"The Emerald Eye," said Ryūji as the blank look grew on his face again. Suddenly, the gem and Slash Breath started to glow.
"What's happening?" asked Rose as the lights grew too intense to look at. When the lights faded, the first thing Aspen noticed was that the gem had vanished from his necklace.
"Where is the stone from my gem?" asked Aspen with a freaked expression.
"It's on Slash Breath," said Gakushu as he noticed the green stone set into the blade of the knife.
"Ryūji, Ryūji!" said Rose as she shook him, trying to snap him out of the trance he was in.
"What… what happened?" asked Ryūji as he finally snapped out of it.
"Slash Breath took the Emerald Eye, may I see it for a second?" asked Gakushu.
"Sure," said Ryūji as he handed over the Lost Precious.
"I since a power in Slash Breath that is similar to what the six race stones give off, it could be that it will take them when in proximity," said Gakushu as he held the blade to his ear.
"Why didn't it take the Ruby Eye then?" asked Ryūji.
"Because you can engage with Rose, meaning it can drain power without taking it," said Gakushu.
"Does that mean I won't ever get it back?" asked Aspen as he wiped away some tears, revealing the green four leaf clover symbol on his left hand.
"Don't worry, I think I know someone who can help," said Ryūji.
