Q: Mr S, can you see anything on the Biribiri Ryusoul that isn't on the other ones? Wondering how it triggers the fins folding up on the Mosa Changer when it's inserted while Gold Ryusoul didn't. (By )
A: Yes, I know what you mean and I think we figured it out. I noticed that one small pin at the bottom right of the Biribir Soul's Code rails which none of the Ryusouls I showed in the demo. It must trigger to open the fins on the side of DX Mosa Changer. According to our chat member, Nekodragon (Twitter: @CSNekoDragon) , there are some possiblities that some Ryusouls can do the same thing as Biribiri Soul.
So it might be interesting try those Ryusouls with DX Mosa Changer next time ;)
Thank you for your question, :D
