Rígr Stafford is his official name.

He could be the Norse god of creation. http://www.thewhitegoddess.co.uk/divinity_of_the_day/norse/rigr.asp

This god has a few different names, including Hemdallr.

https://en.wikipedia.org/wiki/Heimdallr

"The introductory prose to the poem Rígsþula says that "people say in the old stories" that Heimdallr, described as a god among the Æsir, once fared on a journey. Heimdallr wandered along a seashore, and referred to himself as Rígr. In the poem, Rígr, who is described as a wise and powerful god, walks in the middle of roads on his way to steads, where he meets a variety of couples and dines with them, giving them advice and spending three nights at a time between them in their bed. The wives of the couples become pregnant, and from them come the various classes of humanity. Eventually a warrior home produces a promising boy, and as the boy grows older, Rígr comes out of a thicket, teaches the boy runes, gives him a name, and proclaims him to be his son. Rígr tells him to strike out and get land for himself. The boy does so, and so becomes a great war leader with many estates. He marries a beautiful woman and the two have many children and are happy. One of the children eventually becomes so skilled that he is able to share in runic knowledge with Heimdallr, and so earns the title of Rígr himself. The poem continues without further mention of the god.[21]"

I wonder if his name choice has anything to do with the Michaelas. Since Saito is a creature of many aliases, it's entirely possible that Rígr isn't his real name either.
