Yeah collection purposes. I figured otherwise who will buy a manga s/he cannot read? I remember Mamo asking gumb to buy him Yawara manga when he was in Japan and he couldn't figure why Mamo would want something he can't read....of-course it was the collection factor. I started collecting anime vhs tapes back in 1996 when I didn't even know what they were saying. As a matter of fact, my Eriko watching started with not knowing what was going around and by the end of the series I could understand what they were saying without having done any studying on it.
