"Shark, have you seen Yuma?" Yuma's green haired friend asked in concern.
"Nope, can't say that I have." He answered in a cold tone. Kotori glared at him for it, thinking he didn't care.
"Yuma's gone missing and you don't even care!" she yelled at the top of her lungs. His normally cold, ruthless eyes showed clear signs of hurt, which made Tori regret yelling at him.
"SHUT UP! JUST SHUT UP!" Ryoga screamed, running out of the school. He then ran towards Yuma's house, fearing the worst. When he got there he knocked on the door, and instead of hearing Yuma shouting "I'm coming!" he saw his grandmother open the door.
"Ahh Ryoga, do come in." she told him. Her eyes showed clear concern which only made Ryoga's fear worse.
"Is Yuma here?" he asked, hoping she would say yes.
"Well he's here, but—HEY WAIT!" she called after him. By the time she chased after him Ryoga was already in Yuma's room.
When he got there he could see that his room was a mess. Yuma's cards were no longer visible, which is strange for the young duelist. Yuma's tears stained the cover which is when Ryoga got closer.
"Yuma?" he asked with concern, putting his hand on the other's shoulder.
"Mmm?" Yuma muttered, unable to make an audible response.
"Yuma, what's wrong?" Ryoga asked with concern.
"Observation: humans can be sad for long periods of time." Astral muttered.
"Shark, please leave me alone." He sighed, not wanting anyone's presence at the moment.
"Yuma, what's wrong?" Shark sighed.
Yuma stared at Shark with a blank expression before he looked at the ground.
"Yuma?" Astral floated over to his partner and put his hand on his cheek.
"Yuma, look at me." Shark begged; unaware of Astral's presence.
Yuma looked at him though he remained silent as tears fell from his eyes.
"Yuma, what's wrong?" he asked for the umpteenth time.
Yuma sighed as he thought about the last time he nearly lost everything.
"YUMA!" Astral screamed as he hovered over the unconscious boy.
"Yuma!" he shouted, shaking him frantically.
"Yuma wake up, you won the duel!" he called, still frantically shaking him.
When Yuma finally opened his eyes they were practically soulless.
"No! Yuma!" Astral cried.
"Yuma! YUMA!" Shark called, worried at his sudden dazed state.
"H-Huh?" Yuma asked, finally coming around.
"Yuma, what's wrong with you?" Shark sighed.
"I-I nearly lost everything." He sighed, now just staring at Shark and Astral.
