Oh god I never know autobots can transform into THAT!!
Which mean.....Reimu is Decepticon?

Wait...Bkub's Orin speaks?

She speaks, and now I can't unhear her sounding like Lebouf.

I'm pretty sure "gagagigogi" is just supposed to be an onomatopoeia for the transforming sound from the old Transformers cartoon. Either way, most people will probably know what sound it is even if you can't type a good English equivalent.

Oh, I know what it is; it's a fairly standard Japanese spelling of the G1 effect (i.e., a variously mixed string of "g-" syllables). I just lightly bemoaned the fact that I didn't know of/couldn't think of an English-market equivalent.
