While Tsukutomi is a god, this role is open to females as well. Overall Tsukuyomi will be trying to keep the peace in this rendition. The three characters are siblings in the mythology, and as such I see Tsukuyomi as the mediator (maybe because he's the moon) also he does eventually wed Amaterasu so he would try to keep her happy and cheerful because of that.

I am going to use this instrumental, so if you decide to use a backing track please use that one. Feel free to sing acapella though.
