Introduction
A female pilot of the giant mecha and the current Tech Officer of the Illumina Federation. She's said to be a genius retired from the military... Although she isn't particularly interested in fighting, she's intensely passionate about studying and controlling giant machines, almost to the point of obsession.
This is bad! Gronru is stuck in her toy box and can't get out! To celebrate the coming of the New Year, Gronru has a surprise gift for you! Just look at how cute she is, stuffed in there with a pile of toys in that festive red and white outfit—she even tied up her mechanical arm with a pretty bow! Just try to ignore the deadly-looking bomb in her hand...
Did this outfit come first, or did the game that this outfit accompanied come first? It doesn't matter anymore. The important thing is that Gronru prepared this especially for her vacation and entered holiday mode right away after wearing it. Even if she is just going to the aquarium for a day and not the beach.
