You'll need more then that to make a readable story. That could be a scene, or theme,
Or a "photo set." As you say, there isn't a conflict in a story that goes "nice guy summons muscle girl and they play nice." Conflict doesn't mean violence, of course, but there have to be obstacles or problems for them to work through. But if you do this as a series of photo sets, problem solved. A photo set just uses a story to set a theme, so there doesn't have to be conflict or a problem to solve. Just scenes to draw.
One item I want to comment on, since it's something I've had to deal with in the past:
(Apologies in advance if this derails things a bit)
It's been my experience that fantasy can easily lead to undisciplined and poor story. As a result it's easier to craft a story idea first and then make the characters conform to the story. Most people create characters first and then try and craft a story around the character.
I think that the reason that fantasy can produce poorly-plotted stories is because writers do not take into consideration that when you redefine reality to suit your fantasy setting, you have to take those changes into account later on. For example, if people in your fantasy world have developed personal teleporters, it changes a lot of plot options later on. Failing to take that into account can lead to a story where the reader thinks "um, couldn't they have escaped this by teleporting?" There are lots of ways to screw up your story by creating a world where ordinary plot devices won't work.
I don't think it matters too much which you develop first (the characters or the story) as long as you make sure to take the time to properly merge them once they're both far enough developed. Good plot development is the result of spending a good amount of time working out the details and making sure that things fit comfortably.
Oh yeah, the topic... Great work as usual Jed!!!
