yes, i've watched all 3 stages and the extra stage. kinda wished i could have watched 2nd stage in japanese though.
i think you guys are being too hard on the animation quality. honestly, i did think the drawings kinda sucked, but it added character to the different people in the anime. the cg graphics are awesome! the story was what really got me though. every episode ends in a cliff hanger. another funny thing... my friends and i kept saying we wish we could meet someone like mako-chan. she would be the ultimate girlfriend.
i can't wait for the next stages. i don't read the manga, so i don't really know what to expect yet.
