Toge no Jizo Publishing has created a beautiful 96 page book collecting Princess Seppuku (2 mini-comics) and Jessica of the Schoolyard (12 mini-comics, note "Jessica of the Schoolyard" didn't translate well into japanese hence the slightly different and I think slightly better "Boss Girl Jessica"). There's new cover art and a free postcard. Buy it directly from the publisher (if you can read japanese) HERE or from The ComicBook Factory shop HERE. I only have a few copies so grab one while you can... 日本語を練習する必要があります!
