It was dark. Yuuichirou stood in a darkened place. He couldn't see anything. Nobody, nothing. Just him standing in overwhelming darkness. Then it brightened and he saw his friends fighting against Guren. Then, there was… him. He saw himself, defending against the man's blows.
"Get back to yourself, Guren !" The other him said.
He was Mika coming toward the older one, sword ready. She ran with anger to go help "Yuu" but Guren dodged the attacks. She was stabbed in the chest, not unlike how they first met again. But Guren didn't stopped. As he activated the curse, Mika's body was turned to dust. Mika was dead. Anger rose in Yuu's chest. Then came that feeling. The one that awakened his Seraph back in Shinjuku.

Black wings sprouted from his back, his eyes changed to those of the King of Salt. Revenge. It was all that was on his mind. Guren was family, but it no longer mattered. He dared do this to his precious Mika. And he would pay. The Battle intensified. The man fought with vigor. It was all over in a flash. Like Mika, Guren's body was completely wiped away.
"Yuu-san !"
Shinoa and the others came right as Guren's life faded. The other was smiling. But that was not his usual smile. It was cold, cruel. He looked at the squad like they were mere nuisances and ended their lives just like Guren's. His senses came back as he saw the bodies of his family fade into nothing. He cried in agony.

"... Chan… Yuu-chan !"
"I'm sorry ! I am truly sorry !"
He moved, struggled to get away from the person holding him.
"Yuu-chan ! Wake up !"
The voice seemed familiar. So close, and yet so far away. Who was calling for him ? He opened his eyes and looked around. Ils eyes settled on worried-looking Mikaela. Mika was alive. That nightmare felt so real.
"Yuu-chan…"
Mika took his hand.
"You're alright. I'm here, we're here. Everybody is okay."
He felt like crying, but they were tears of relief.
"What was that nightmare about ?"
He didn't want to talk about it, but figured that he would feel better.

"I was fighting Guren. Then you came… And… and… He…"
"You don't need to talk if you don't want to."
"He stabbed you… And then… Cursed gear… He activated the curse. You … You…"
Mikaela could tell what came next. And seeing Yuu's troubled face, she didn't want to force him to talk. She knew the trauma he felt from seeing her dying, how he left her to die. Mikaela herself suffered from it. From guilt, guilt of not being able to protect those dear to you.

"But seeing you die, for real, right in front of my eyes… I awakened that thing in me."
He meant the Seraph of course.
"I killed Guren… And… Shinoa and the others… I… I'm scared Mika. I can't control that creature… What if…"
Mika took him in her arms. She rubbed his back slowly.
"You will be okay. You're strong. I know you are."
And she remembered how Shinoa brought him back to his senses. There was a pang of jealousy in her heart. One that was out of place.
"We will bring you back if it happens."

It had been a restless night, to put it lightly. Mika kept rubbing Yuu's back until he calmed down and could go back to sleep. Since it was not necessary for her, Mika chose to keep watch in case Yuu had another nightmare. She swore to protect him. But despite the reassurance she showed earlier, she was afraid too. She saw with her own eyes the Seraph of the End experiments. What if Yuu ended up being lost forever ?

Yuu did sleep well following his nightmare. But being kept aware up to 1 in the morning had its effects. The squad was planning to leave at 9. But Yuu was sleeping so peacefully. Mika didn't have the heart to wake him up, even as the scheduled departure time grew closer and closer. Five minutes before the time, she heard knocking at the door. Waiting a few seconds, the door then opened to Shinoa. The squad was initially willing To let them sleep. But it was time to go. Mika made a sign "five" with her hand and Shinoa left. When the door was closed, she shook Yuu's shoulder lightly.
"Yuu-chan, we have to go."
The boy stirred but didn't seem to wake up.
"Yuu-chan,"

She repeated her actions. Even if she was willing to let him sleep, they had no time. As much as she loathed to go back to Sanguinem, they had a mission. After being shaken for the second time, Yuu opened his eyes. He sat on the bed, a obvious bed hair and eyes half-opened.
"Ah, good morning Mika."
"Good morning Yuu-chan."
She gave him a few seconds to wake up properly before adding :
"You should get ready. The squad is waiting for us."
"Fine. Don't look."
She thought it weird. She saw him in nothing but underwears. He often took off his shirt when she fed from him. She still did as he asked, not without looking for a few seconds. When she saw that he was not just taking off his shirt and pants, she turned away, cheeks red.

Outside, the squad was getting ready. When Shinoa came out of the house, alone, Kimizuki asked her :
"Where are they ?"
"They should be there any minute now."
It was not long after she spoke that the door opened again. Mika came out, Yuu behind her. Both carried a bag. Yuu seemed somewhat half-sleeping but no one commented on that.
"Yuu, is your demon…" asked Mitsuba.
Yuu's demon sometimes caused them problems, which was as worrying as the Seraph.
"It's okay. He's asleep."
He then added in a more joyful voice :
"Let's go. We're gonna bring back Kimizuki's sister and that idiot Guren !"
With that in mind, they started to walk on the beach.
