That fact is potentially troubling, but everything else about the game so far feels like it's going in the opposite direction thankfully. The character designs so far have all been very practical and not fan service-y, the story and setting seem much more serious and well developed. We have actual location names, a deciferable world map and solid details about the setting. And overall it seems to be taking more design cues from Echoes than anything else.It looks like it takes place in some kind of school setting right? I saw the trailer but haven't followed up on it. School setting doesn't really scream FE to me haha. Screams, every other cliche anime trope incoming. I'm hoping I'm way off base though, because the armies fighting around the battles looks fantastic, among other things.
But yeah there is always the possibility of some high school themed pandering and fan service. Hopefully we'll see more very soon and get a better idea at the direction this are going.
