**UPDATED: https://nyaa.si/view/1117639**
Downloaded from http://sai-zen-sen.jp/comics/twi4/tomochan
Both files contain the first 722 strips, downloaded from the site. The png version has somewhat noticeable better quality but has a small "ad".
For comparisson:

The code used to download these pages is below for anyone interested, but note that it doesn't work for the newer pages (after 722 last time I checked). The URL scheme has changed so now it requires processing HTML to find the images URLs.
