"Our pinkies aren't for the sake of making pinky promises…"- Radwimps 'Yubikiri Genman'

"Yukio!" I screamed as I hurried towards the eastern part of the academy. I heard that there was a demon had snuck in the academy and Yukio was one of those who were assigned to kill it. But for some strange reason, I felt something bad was happening. That sudden ache in my chest which made me feel my insides twirling. And that I dropped his lunch box on the floor with my hands shaking non-stop.

I was scared.

"nii-san…"

When Rin finally reached to where his brother was…

It was too late.

"Yukio! I'll protect you! I'll make sure that no one will hurt you again and if they still continue. I'll beat them up for you! I promise!" Rin showed his pinky finger to the teary eyed Yukio.

Rin's legs wobbled as he tried to walk normally towards to his brother who was hugging himself on the ground. Just like the old times, when he saw Yukio crying because someone had bullied him.

While Yukio's party were all on the floor all lifeless. Yukio remained alive, but there was something different from him.

Yukio's glasses were on the floor broken in two. His coat was on the ground as well all torn up. The buttons of his white shirt were opened as well. Rin gulped, 'This is bad.'

"Y-Yu-Yu-ki-…" Rin tried not to stutter.

"Get away from me!" Yukio screamed as tears were evidently flowing down to his cheeks.

"B-but…"

"N-nii-san… I… hate you…" Rin's eyes widened.

What had happen? He tried to reach out. As one of his hands were few inches away from the younger twin. Yukio quickly slapped Rin's hand away.

"D-demons…" Yukio said biting his lower lip and hugs his legs tightly, "I'll kill them all… even you… Rin…"

"Even you…"

"Tou-san, I will protect Nii-san!" Father Fujimoto smiled as he saw that determined look that little Yukio showed.

"Promise." Father Fujimoto showed his pinky finger to Yukio.

"Uh uh!" Yukio hooked his pinky finger on Father's then smiled.

"Well then, no matter what happens protect him alright?"Father Fujimoto placed his other hand on the child and ruffled it.

"Don't leave him, because older siblings depend on their younger siblings a lot."

"I'm sorry… Tou-san looks like I won't be able to fulfil that promise anymore."

P: Alrighty! Hahaha That's my first AoEx fanfic desu! I got hook up with it because I like 2pm's 'take off' and I decided to watch it and bam! My lil' bro and I are now fans! Hahaha... Anyway this was inspired by a song from Radwimps entitled 'Yubikiri Genman'(Pinky Promise)
