Note: What Suboshi might've felt the day Amiboshi "died".

Evaporating Ki

"Amiboshi? Amiboshi!"
What's happened? I feel so lost. There's something of me missing? What is it? Aniki. If aniki were here, he'd know. He knows so much. He could tell me what I've lost. Wait...aniki?!
"Aniki's chi gone. I don't feel it any longer."
Aniki! What has happened to you? Why is the presence of you chi no longer in my soul? Where's it's reassuring warmth? I'm searching my soul, searching, but I don't feel you. Aniki!!
"Was he killed...by Suzaku's seishi?!"
They can't have done this to me! Taking your life...the greatest crime. You are the only one I have, the only one I love! Nakago, why did you send aniki to Konan, if it was to die? Oh, aniki!!
"Aniki! Aniki!! Nooooooo!!!"
They have taken you from me. Now I'll live only to kill them. I will avenge your death. I have lost what is most precious and important to me, so that I will take from them. It's all right, aniki.
"Never get away - me wo hazurasu na!
Never get away for you!
Suki wo misetara yararechimau kono destiny!
Never get away - sekai-juu ga!
Never get away for you!
Teki de mo kamawanai -
It's all right - kimi no tame!
