Dohna Dohna:Second Game Bonuses

Endings
Dohna Dohna has 8 different Endings:
 * 6 unique heroine endings: End the game with a heroine with at least Level 8 by Episode 23. If you have multiple, then you will unlock the ending for the heroine with the highest Feeling stat.
 * Mistress ending = End the game with no heroine's Feeling level higher than 7 and must obtain Mistress CG by visiting the shop with at least 20,000,000 Yen before Episode 23.(Note that you will still get Mistress ending even if you hustle Porno before doing her Haken during Episode 23)
 * Normal ending = Fail all other ending requirements or hustle Porno before doing her Haken during Episode 23.

You can theoretically unlock all the endings and collect all the CGs in a single run by going back to save files to see bad ends.
 * See the CG Guide Tips for ways to get CGs efficiently.
