Hatoful Boyfriend is a dating-sim with a deeper scenario that it seems. There are secrets and mysteries to discover at St. PigeoNation.
This guide will not detail how to get a particular ending, but propose an order in which try to get the endings, so the story is discovered in a more enjoyable way. The first scenarii recommanded are the ones with less informations about St. PigeoNation mysteries, then the remaining ones are sorted in the order that I found more logical.
Each scenario gets to a different ending, so they are not following each other. The order I propose is subjective and purely optional : you can enjoy the game in any order!

Some pictures are from the original version of the game, the UI is different but the artworks stay the same.

1 : Kawara Ryouta
The friend of your childhood. This is a good way to get started and attached to the characters.










2 : Shirogane Le Bel Sakuya
The arrogant aristocrat. This one has two very similar endings. One is more complete than the other, so it is a bit borring to do it if you already completed the full ending, but you can accelerate the scenes you already saw. This is the case for all the pathes with two endings.





3 : Okosan
The feral dove. The craziest ending of the game! I advice you to save on the 8/30 since you can have two different endings from there.







4 : Nanaki Kazuaki
The sleepy mathematic teacher. This storyline is a bit heavier in terms of scenario.








5 : Koshiba Azami
The badass java sparrow lady. As Okosan, this ending is not really related to the main plot, and can be done anytime you want to explore this secondary plot. There are two endings for her.









6: Fujishiro Nageki
The quiet mourning dove in the library.









7: Iwamine Shuu
The creepy doctor. He has two endings. Some may prefer to do Yuuya's story first, it's a matter of taste!








8: Sakazaki Yuuya
The ladykiller, and Sakuya's half brother.

9 : Higure Anghel A secret character. You have to unlock Yuuya's ending before being able to meet him. His road is a funny one. (Thanks to the people who gave me that information!)







10: ????
A secret story and ending! You can unlock it by doing Ryouta, Sakuya, Nageki, Yuuya,
and Nanaki's endings, but it is recommanded to keep it as the last path because it is the most complete story. Once it is unlocked, another choice option appears at the beginning of the game, allowing you to get this scenario. It is quite long and you may want to do it in several rows... Or not!
