It would've helped make our Protagonist a bit more likeable if I saw these friends he spoke of. As of now, he's just some guy bulldozing cool dudes with feathers (which is kinda disappointing).
At the very least, we get to see Rihaku's traps be effective. Raoh bested them like a speedrunner for the most part.
EDIT: AAAAND we've been waiting 8 years for the final chapter. COME ON!
