This is the English version of the spin-off manga work from my own novel "Girls world". The entire book is in full color and can be enjoyed whether you have read the novel or not! (Characters from the novel version also appear.) It is also available on a smartphone, but since it is produced on a tablet, the colors may be more beautiful and easier to view on a larger screen of the medium you are viewing it on. There are some pages that are in black and white, some text pages explaining the situation, and some difference pages, but the total number of pages is 120 including extras.
