So never seen a game do this . I need to beat 50 more episodes or S rank 5 episodes to play the real end for 18? Any tips on a fast track? like the easiest episodeto beat/shortest so i can just replay it 50 times or the eassies ones to S rank? And i wonder is the first 18 episodes count towards the 50 episodes? Any expanded info would be helpfull thx!

Just go through the chapters on easy and do the jump kick into the move that knocks enemies into the air as it gives you a lot of battle points. The thing that often stops you from getting the S rank is the BP as the sync and the time are easy to get if you play on easy. It also counts S ranks from all difficulties so you could have 1 on normal and 4 on easy and it would still unlock.

I played through on easy and got the 5 s ranks while normally playing through the game.

Just play on easy and skip every cutscene. It might be a bit tedious, bit it makes going through the game pretty quick.

Or you could just look it up on youtube, it's really just another minute added to the normal ending.
