Oni no Hana Sagashi
In a modern world with several old families descended from animal spirits and monsters, ogres are known for being especially romantic as they fall in love only once with their "blossom of fate." Hana is busy working at her adoptive parents' restaurant and assumes rumors of the young ogre lord searching for his blossom have nothing to do with her, until she meets the ogre Mitsuki and feels the spark for herself. This story is all over the place. It's as if every chapter they introduce a new conflict only to either resolve it or forget about it by the end of the chapter, and yet it also feels like nothing really happens, perhaps because it doesn't build up enough. It wasn't compelling, but the boyfriend was good about consent, so there's that. If you want to read it for the smut, go ahead. No trigger warnings.
Oni wa Shitau wa tatarigami
Tsubakimaru is a young half-ogre orphan who was kidnapped when his captors suddenly died and he met, Shii-sama, the evil god of the mountain, turned into an evil god when humans cut down his tree. The lonely god is overjoyed to find that the young child survived due to his oni blood, and Tsubakimaru decides to stay with Shii-sama to help him not be lonely. But as he grows, the excessive lust that onis feel begins to become a problem for the pure-hearted boy, while Shii-sama feels he needs to set Tsubakimaru free. But even as Tsubakimaru and Shii-sama are beginning to figure out their relationship and the mountain seems to finally be healing, villagers who see the young ogre become convinced they must destroy the evil god again. This story was 90% of the way there to being a tragic masterpiece, but then it just suddenly deus ex machinas it's way into a happy ending that doesn't really make sense. Also for some reason it decided to go with a weird tentacle hentai thing for a lot of the sex scenes, but hey, I don't judge. The relationships and characters are really well done though, and it's still worth a read. Trigger warnings: incest themes (guardian).
Onihebi Kyuai Monogatari
Chiaki is lonely after the grandfather who raised him died. Fortunately, that's when Benio the oni and Yue the snake spirit both arrive announcing it's time for him to fulfill his promise to marry each of them. The two begin fighting over him, and although Chiaki is surprised, he ends up enjoying the new lively atmosphere so much, he can't begin to choose between them. This one is more smut than story. ️Trigger warning: noncon, attempted rape.
