The web version of BookWalker does not provide original images. Each publisher uses different encryption methods, resulting in varying file sizes. However, the original image specifications are uniform — there's only one true size. Files captured from the web version do not match the original in size, except for those from Shueisha, which hosts the original images directly on the web version.This is also the reason why some digital artbook galleries have drastically different file sizes, and why images in some galleries suffer from severe JPEG artifacting.
The original file of this BookWalker volume is in JPG format with quality level 10, and a total size of 87.7MB. Although it appears to be of good quality, closer inspection reveals some artifacts. This gallery has manually restored the image to remove JPEG compression artifacts and saved it using the highest possible quality settings, preserving maximum visual fidelity while minimizing file size.
Therefore, I will work, I will save, I will sacrifice, I will endure, I will fight cheerfully and do my utmost as if the issue of the whole struggle depended on me alone ——Instrumental Present
