Does Anyone Know This Japanese Song?

[Akimin]

I've been trying to search this song for some months now and I hardly have any information, though I try to describe it the best I can.
It is Japanese and sung by a male with a guitar. The song and the guitar are somehow powerful, but I think it was a sad topic. The only lyrics I remember was when the male sang "Kudasai na!" in a kind of sad but strong way. It was the most powerful part of the song. I'm really not sure with this point, but I think the words samurai or osamuraisan (dont know if they mean the guitarist) were in the title. Everything was written in Japanese, I guess. I've found the song as it was recommended to me on YouTube after some videos after PonPonPon by Izaya Orihara.
I hope you know what I mean - thanks for any help!
