I was struggling over the series some weeks ago
I love to fool a round with story's far a way from the main character its like stretching for the mind.
So if Makino build the Ulta-links thy don´t need a gender but in the series and at your wikia it seems like there are male and female ones is that correct ?
So what are the differents? and if thy male and female thy must be able to breed.... And don't tell me its the color only.
and one more
Steel is eating energy right? So will all Ulta-links starve to death with out energy I mean thy link to almost everything . Did Makino feed them?
Thats all at the moment.
