Makai Princess (game series)
The Makai Princess series is three H-game titles with the same basic plot, just split into three separate games based on which girl the protagonist picks.
The basic story is as follows: (from VNDB's page on Princess Eris (NSFW))
Souta is a pervert, there are three girls living next-door and he knows every tiny detail about them. His parents are abroad for business, so he is taking care of them for now. On Arisa's birthday, they tell him that they are daughters of the Devil. Souta isn't surprised to hear that. They are relieved and tell him why they live in this world. Their purpose is to find a partner and prevent their race's extinction. They suddenly tell him to choose a partner among them...
The three games in the series are:
- Amaane Makai Princess Eris wa Eroicha Haramizuma! ~Suki na Dake Dashite Zenbu Shikyuu de Nonde Ageru~
- Tsundere Makai Princess Arisa to Haramase Shinkon Seikatsu! ~Zenbu Dasu made Nuicha Dame! Zettai Jusei Sasenasai yo ne!~
- Coodere Makai Princess Sara to Kyuusei Haramase Life! ~Suki na dake Shikyuu ni Sosoide Ninshin Sasenasai~
As all three games are the same aside from the one choice mentioned above, all three shall be covered here.
- Cool Big Sis: Sara, to the point Souta almost considers her out of his league.
- Fan Translation: Only Eris' arc has gotten a translation so far.
- Freaky Is Cool: Souta quickly adjust to the fact the girls he grew up with are actually devils pretty quick. Then again, he always liked them, and they only got MORE sexy in their true forms.
- Kinetic Novel: While they do have a few choices to alter events somewhat, the plot is short and linear in all three stories.
- Kuudere: Sara, as mentioned in her game arc.
- H-Game POV Character: Souta is a somewhat perverse but well meaning Type 1, and when forced to choose between his baser mores and keeping whichever girl he chose happy, defaults to the latter every time.
- Hot as Hell: All three girls are the devil's daughters, which is close enough.
- Hot Mom: All three become this in their respective endings.
- Innocent Fanservice Girl: All three in their demonic forms are this because to devils, their skimpy dress is quite normal.
- Horny Devils: Technically, this is but incidental really, as all three want to have Babies Ever After for racial preservation reasons, but that doesn't mean they aren't enthusiastic about pursuing this, and in their demonic forms they certainly look the part.
- Nice Girl: Eris fits this trope to a T.
- Satan: Souta's father-in-law, a fact he is not very troubled by.
- Tsundere: Arisa, as mentioned in the title of her game arc.
- The Three Faces of Eve: In terms of temperament, Arisu is the Child, given her Tsundere attitude. Eris is the Seductress with the personality of the Mother (being the most domestic of the three), while Sara is the Mother with the Seductress personality (being the most adult of them all in appearance while being the emotional anchor for the girls).
- WAFF: This is a pretty feel good game. Even the hentai scenes are drawn in a soft style with loving dialogue and the kinks are pretty vanilla and consensual.
