What can you do if you want to play kingdom hearts especially 358 2 days but your parents think it is violent

well first i have played all the games and by opinion i say none of them are very violent and i am a christian and still say this.but first if you are wanting to play kh 358/2 days without playing the others you are wasting your time because you WON'T understand it unless you have read online summaries on it . but in all the games there is no cussing or blood or anything like that in less you are in pirates of the cairabean that's what it means if it says mild blood on the rating and people die in the game but they just wither away into darkness and a good example of this is a video on kh vids.net or you tube video on the demyx fight.but you could show your parents videos online from the game and the square enix company is teamed with Disney so the king is mickey and sora the main character is acomponied by Donald and goofy,and i don't know what kind of violent game that is!
