Spoiler:

Shiryu and Shunrei both made a cameo appearance, but no words were spoken.

So apparently Shiryu lost his five senses in the last battle and trained Ryuho by cosmo synchronization/communication - which explains why Ryuho has a high grasp of his own cosmo as well as being sensitive in sensing cosmo of others, and can even tell how the enemy will move and attack according to the follow of cosmo in their body.

The fight between Kouga and Ryuho is referencing a lot of the original Seiya vs Shiryu fight, I think the writers added the new elemental attacks in hope to fix that stupid "same attack won't work on a saint twice" hole (but the bronze saints just keeps throwing them out again and again and eventually will work in the original work) since it's adding a lot more medium special attacks to the fight - to put it in a fighting game analogy if we take Street Fighter as an example the elemental-fused attacks will be like a Hadouken or Shouryuuken and the super specials like Shinku-hadouken or Shinryuuken will be the Ryuuseiken and Shouryuuha.

Have to say that it was pretty nostalgic to see Ryuho throw a Shouryuuha (and one shot which looked almost like he did an Excalibur too) and we got a bit of the old Saint Seiya style flying bodies and hard landing for the old farts to enjoy, but apparently he can only use it once due to his own frail body. I can see this plot point will be used a lot later in the series...

So who won the fight between Kouga and Ryuho?
I seriously hope Kouga gets his first win.
