I believe i made a small mistake when i said i managed to complete 100% the kingdom hearts 2.Well that was one XD but because i didnt wanna let myself down i stayed and completed the game at 100% and trust me it was way too tough but i managed thank goodness at proud mode always and believe me Sephiroth was the least of my problems in the game as the minigames were really tough also.This is the song that  made me do all this.Enjoy it as much as I did + I indeed cried during the game.As for some comments i did thats because i saw my best friend playing it and he didnt manage to end it at 100% because he just wanted to beat the story mode.As for me well always looking for a challenge XD now enjoy
