Iíve noticed a couple people who have read the RAW scans and didnít understand what was happening, so I wrote a summary of the last volume. If youíre dying to know what happens in the end and you donít mind being spoiled, feel free to check it out as well.
You can find it here. (The link goes directly to the post, so don't click on it if you aren't interested).
If you have any questions, please ask them at the post.
