Yukio suddenly sat up from his seat, surprising everyone in the room. His hands were beside him, trembling. He stumbled into Rin and hugged him. He buried his face at the crook of Rin's neck.

"Why...why can't it be anyone else? Why you Niisan?" Yukio's voice cracks, Rin can feel the wetness of his shirt from Yukio's tears.

Rin smiled broken heartedly. He hugs Yukio back, tears running down his face. "I-it's okay, Yukio. Everything going to be al-alright."

Shiro closed his eyes. His children, God have mercy, his children. He walked towards them and embraced Rin and Yukio. His tears mixed with theirs. He never wants to let them go.

The next few years was hell. One morning, Shiro woke up to find Yukio shaking him, telling him that Rin have a really high fever.

Shiro immediately rushes to Rin and Yukio's room. And found Rin sweating, his breathing ragged. He keeps coughing every few minutes. His sleeping face looks exhausted.

Shiro puts his hand on Rin's forehead, and quickly recoiled when he felt how hot it is.

"Get some medicine and a thermometer, Yukio." Shiro said. "Rin's definitely staying on bed today."

"O-okay," Yukio stuttered, rushing off to get the desired supplies.

Shiro gets a wet towel and puts it on Rin's forehead. He frowned,'This is bad, Rin's body is already weak, if he gets sick it will only aggraviate the disease.'

Yukio came back with the medicine and thermometer. He gave it to Shiro and sat down besides his twin. He looks worried while Shiro took Rin's temperature.

"Is Niisan going to be okay?" His eyebrows furrowed and his fingers twitched with worry.

Shiro clicked his tongue, the thermometer reads 103 F (A/N: 39.4 C). "He's going to be fine. He just needs some re-" Shiro was cut off by the sound of Rin coughing. He have woken up.

Rin continued to cough his lungs out. Mucus gargled at the back of his throat. Tears gathered at his blue eyes. He grabbed his throat. He can't breathe.

Shiro and Yukio immediately jumps into action. Shiro rubs Rin at the back and whispered comforting things at his ear, while Yukio pried Rin's hands from his own neck, not wanting Rin to hurt himself.

Rin started calming down and his coughings have subsided. Blood leaked out from his nose. Rin wiped the blood with the back of his hand. He looked at Yukio with pained half-lidded eyes.

"Yo-you should *cough* b-be at school." Rin sniffed, his fever-clouded brain made him forgot that it's Saturday.

Yukio smiled, worry clear in his teal eyes. "It's saturday Niisan. There's no school." He looked at Shiro, concern all over his face.

Shiro ran his hand through Rin's hair. "Sleep Rin, I'll wake you up later for lunch and your medicine."

And Rin did sleep. And when he woke up, Shiro and Yukio was there, taking turns at taking care of him.

=UNSEEN=

"Shouldn't Niisan's demon blood have protected him from the disease?"

Yukio's question made Shiro stop reading the reports for the attack at Nagasaki. Apparently a fox demon recked havoc at some market and some citizens are caught at the crossfire.

The question made Shiro frown, "I'm not really sure, but maybe it has something to do with the Kurikara being sealed."

"Then should we-"

Shiro cut off Yukio before he can finish, "We can't Yukio, if Rin ever draw the sword, there would be dire consiquences."

Yukio seems to have an inner battle with himself,

"Okay."

But in the end, the rational part of Yukio's brain won.

=UNSEEN=

They say that the best people seem to have the worst luck. And apparently, that's true.

Because for Yukio, his Niisan is one of the best people in the world. When he was a child, he always want to become like his older brother. Kind, brave, sincere and head strong. When he started training to become an exorcist, he can't help but be jealous on his brother. Rin can have all the free time he wants, while he needs to push himself on his training.

But when his brother was diagnosed, everything changed. Rin can no longer play outside without coughing up blood after. Rin can no longer run in a long period of time, cause it makes his lungs weaker. Rin can no longer protect Yukio from the bullies, because he became too frail to do so. Rin became restricted on so many things, that he can often be seen sad and solemn, looking outside the window. The only thing that he is allowed to do is cooking, and only because he begged Shiro to still let him cook. It made Yukio pity his brother. While he needs to train to become an exorcist, he's not restricted on doing things he enjoyed.

It made Yukio realize how unfair the world is.

Because while he trains how to use a gun to become an exorcist in the future, Rin is bed-ridden at the monastery, sick and looking out the window, hoping for a future that is non-existent.
