Buy it if you can to support the artist.

Thanks to wocle if I could decrypt this.

Thanks whr86.

This has lighter censorship than the magazine version (some pages are even uncensored), and Ornitho2 chapter 4 looks considerably more polished (e.g. here vs. magazine).

The magazine versions of Ornitho and Ornitho2 have both been translated to English by Munyu:
Ornitho chapters 1-5
Ornitho2 chapters 1-5
