Ok, I went in the direction of Satoru being a summoner. I am probably going to keep his number low as to how many he will eventually have access to. A deity's companionship is more or less treated as a limited agreement of availability in which they may be called in times of need. These are all temporary and the terms can be relinquished at any time, pending a final exchange. His first will be a healer as denoted in the very brief character sheet. There is also a picture of the diety as well, or at least the closest image of something I could find of a healer type. Outside of his summoning, there is nothing special power wise that I have decided upon. Let me know if everything is alright as character sheets are a bit of a hit or miss at times.
