I've come across a translation, but I'm not sure if it is accurate. What do you think?
"漢たる死に安らぎなし
曲折の果てに其は訪れん
人に非ずとも 悪魔に非ずとも"
"Death's vastness holds no peace. I come at the end of the long road, neither human, nor devil."
"我が意思の逝くまま"
"All bends to my will"
I found it randomly in a very underground site (by searching the Japanese sentence). Do you think the translation is accurate?
