An ocean city, Tristia.
Tristia used to be prospering playing an important role of the maritime trade, and it was as beautiful as to be praised as "marine jewelry".
However, that was a long time ago.
The attack of the dragons deprived the city of their original brightness. The people in Tristia worked hard to reconstruct their city, but everything they did went wrong, and the city became desolated on the contrary.
At the end of their hope, they asked a Great Artisan for the recovery of the city, Prospero Flanka. Prospero was a legendary inventor who had revived cities that otherwise would have been ruined.
The long-awaited day came when the Great Artisan Prosper arrived in the city... However, it was only one girl who stood at the port of the city. Prospero sent his grand daughter, Nanoka, for him.

There is a mysterious man seemingly behind Panavia ...

Mixed Feelings
Aoi Umi no Tristia certainly would appear to have a lot things going for it, upon just looking at the picture you might feel its a cute shoujo with lovable characters and a heartwarming story, and while it does indeed have it in this two episode OVA, its a shame that it does it so by the book!

Story: 5/10
Well there isn't much to it, basically it has Nanoca (our young heroine) fighting battle after battle by way of her own huge mecha called Golems which she herself created, and at this point I was instantly reminded of Pokemon and Yu-Gi-Oh, but with robots! Which honestly, ...
