Well, some may have wondered why bunch of chapters / titles have been disappearing recently. Some might not have noticed at all... As part of METI thing happening, we're getting quite a few dmca requests. As our policy, we are complying with the requests and they have been removed. I do expect to get more notices in the future.
Please do not ask me or any other staff where to get them or if you can download them. The answer is no.
