[JAP -> ENG] Nobuaki Kakuta - (Yossha) Otoko Uta

Nuti is back! with a translation request.

I'd like to get the translation and maybe the romaji lyrics of this song (MMD video, I couldn't find the original one): Otoko Uta. Googling tells that the song was sung by Nobuaki Kakuta.

The song is that lively that I want to know what's said in it
