Interesting concept and presentation, I'd like to seem more explicit illustrations. But this is pretty good as is. ESPECIALLY because each page is a metatextual diary entry that has itself been illustrated. That's why I'm giving this 4 stars! Excellent!
Forcibly changing a legal identity, throwing out your possessions, and manipulating your brother to act like a 15 year old little sister due to inexplicable events, while throwing them into highschool of all things (because this whole ordeal didn't seem to add enough stress apparently) isn't normally something I would excuse as tolerable behavior. But in porn land it certainly is. That or anime land maybe.
