Grand Order of the Elder Elemental God

He didn't know what he would think when he found himself waking up on a bed, being met by a girl that looks like... like... isn't it Mashu Kyrielight from that mobile game, Fate/Grand Order...

And yet, thrust with the responsibilities of saving mankind from its incineration while trying to make do with the Avatar he had suddenly turned himself into, Aelder, alongside his Kouhai, his Servants, both native and new, are gonna save this world, one step at a time.

Although, that doesn't mean he won't have some fun along the way ;)
