Ｔｒａｎｓｌａｔｉｏｎ　Note : English translation line 5. from...
胸の奥で疼くのは天地不明のパラグラム
Translated to... Aches deep in my chest are because of ignoring to the destiny the world granted

Tenchi (I assume this is "The sky + The earth -> The world", a dying Chinese composite word, but still widely used in my language ;p)
fumei (unknowing -> ignoring)
paragram (a pun. In this case, positively probably, what have been occurring in the world -> destiny)

The existing (what aches inside of me is a paragram that doesn't know up or down.) one (ONLY this line) maybe too rough. Maybe since my English is poor, I could barely understand it. I don't know if it's alright not to include the world "paragram" in the translation, since it doesn't have literal meaning.

Suggestions or editings are appreciated.
