The strange incubation process reaches its absolute breaking point! Pushed to the limits of endurance, the intense swelling finally gives way to a massive release of accumulated energy. As the cycle completes, a chaotic surge of magic triggers the most extreme physical upgrades yet, unlocking a brand new harpy form. But as her body adapts to these monumental changes, a dark and unexpected secret about the mysterious tree is finally revealed.

I will be sincerely glad if you can support me on Patreon/SirNrei, there you will gain access to new chapters of my comics a month or two earlier before I publish them publicly, and you will also get many other bonuses. Thanks to everyone who already supports me, this is extremely motivating to work further and create better comics.
