Still Alive - Portal [Romanization]

So apparently there's a Japanese version of the ending song to Portal (Still Alive), and someone asked for the romaji of the kana used in this video. Since I fulfilled that request, I figured I'd post it here too, in case anyone should ever want it. The lyrics are rather sadistic if you ask me!

Seikou yo
Kono kiroku wo nokosou
Subete wa watashi no omoidoori
Apachaasaiensu
Yarubeki koto wo shiyou
Sore wa ikiteru hito dake no tame
Shippai suru tabi naite mo
Shigata ga nai
Keeki no tame ni yarinasai
Soshite subarashii juu dekimashita
Ikiteru hito no tame

Okottenai yo?
Totemo ochitsuiteru
Anata ni korosareta kedo ne ~
Hikisakare
Hi no naka ni nagekomare
Sugoku kurushii
Demo ureshii yo
Deeta no ten ga awasatte
Kanseihin ga dekiagaru
Dakara ureshii
Karada ga moeru
Ikiteru hito no tame

Oite itte
Watashi wa koko ga ii
Anata wa betsu no dareka to
Sore wa burakkumesa?
Nante ne joudan yo
Shikashi kono keeki wa
Totemo oishii
Kagaku ni tsuite wa makasete yo
Anata ga inai to ureshii ne
Watashi wa korekara jikken da
Mada ikiteru hito de
Mada kokode watashi wa ikiteru
Kagaku wo suru no ikiteru
Totemo ii kibun ikiteru
Anata ga shinikaketemo ikiteru
Anata ga shinde mo ikiteru
Ikiteru
Ikiteru
