Why hello there Selamat siang ^u^ I thought you were Singaporean.I tend to think Riku just wasn't ready to face those whom he had caused so much pain just yet, and was afraid that the darkness that he was holding in his heart would hurt them again. Probably that was his idea of seeking redemption, too.
Just noticed that you're my fellow countryman. Selamat siang~
Anyway, I haven't been following the series lately due to lack of consoles and the munny to buy them
And I'm still confused about the events in DDD (now they can time travel? urgh what next?) Not being able to play all of them will eventually give you a headache trying to figure out the plot of the story and trying to piece them together is near impossible for me -_- I just hope KH III will shed some light to the missing puzzle pieces of the plot.
