Long live the SRW games. I love them.
I would like to add Star Driver, Heroman, Gaogaigar, Gundam Age, and Aquarion Evol.
In Haruto's view point, there are other units. But for the viewers, us, we can only speculate them as parts from our view point.
But ultimately, we just have to see it next week. And I think someone had already said that they're individual units.
Saki Comeback; "comeback" is a slang term that means a smart retort.
