Can you please put the alternative bad end chapters right after their main story chapters? Like chapter 1, chapter 1 bad end, chapter 2, chapter 2 bad end.
The bad end chapters chronologically and logically follow their respective main story chapters.
Not all chapters have alternate bad ends. The ero trap dungeon one doesn't seem to be related to any main story chapter.
And most importantly, the artist/creator himself separates the two. The bad end chapters are numbered sequentially and not matched to the main story chapters-- for example, Chapter 9 has a bad end, but it's titled IF 6 (being 6th bad end chapter) and not IF 9.
If you mean a bad end IF for chapter 17, I completely agree. I see 3 points where bad ends can branch out from:
1. Mysterious person doesn't appear, so the goblin elder has his way on a bound and gagged Astrea.
2. Goblins drain her energy core completely, undoing her transformation. She gets carted to the orcs, who hold a grudge.
3. She succumbs to the pleasure and willingly becomes their slave.
I prefer the last one. The first two are defeats due to being in unwinnable situations, but the last one is a complete defeat because she loses the will to fight and chooses to indulge in sexual pleasure.
If anything, Astrea has a lot of willpower. In other stories, the combination of hostage, aphrodisiacs, goblins, bondage, and energy drain would've been more than enough for a bad end, but here she makes a thrilling counterattack, and though comes up short, she still manages to save the hostage.
