Luna used to lounge on the sofa watching pre-recorded cupcake documentaries or spend time chatting with his BFF (rubber ducky) in the jacuzzi. But ever since he agreed to his twin imouto Corona’s request to make everyone happy, he has no time for that! He’s been busy selling homemade ramune with his osananajimi Lamune, hanging out at the Cherry Crown Diner run by his friends Rayla and Iris, and going out on road trips over the weekends (with Corona and him taking turns at the wheel). Together with his friends and lover, this isn’t just happiness… it’s perfection!

The theme of the game is ‘”All Ways” Be Happy’, depicting a happy and carefree lifestyle. It’s mainly a comedy set in the resort town Saint Aria, where magic and technology co-exist.

A bright and pure boy, Corona's older twin. He spends all day bathing naked in his jacuzzi. He's extremely popular with men for some reason, especially with foreign men. Luna and Corona's parents are famous engineers and sometimes even appear on TV. Because their parents are always traveling Luna and Corona live by themselves.

Despite being very good friends with the heroines, he doesn't allows anyone inside his jacuzzi except for himself and rubber ducks. He has a weird personality where despite being naked all the time, being seen without a problem, he is very embarrassed being seen changing or seeing naked girls. He's also becomes embarrassed by romantic/erotic stuff other people does, especially females. Just seeing panties his faces get red, he freezes and after some time runs away in a panic. He doesn't get dirty jokes and innuendos at all. Great fan of disco.

The story starts when his sister asks if he's living a happy life and invites him to make everyone happy. After thinking whats happiness for him, he realizes he doesn't really care about his happiness and decides to make everyone, starting by his closest friends, happy.

Luna is the town's hero as he can make almost anything from stopping a downhill baby cart to defeating octopus-like destruction gods. Because of this he's hired by RMC to do exactly that. Even though he's that amazing he's very simple-minded and doesn't realize all the girls around him love him.

Luna's and Coronas childhood friend. Daughter of ramune makers, she always loved ramune and if she doesn't have some ramune, even for an hour she starts shaking and having vertigo, also any ramune tastes delicious to her if she drinks in a ramune recipient, no matter how bad it really tastes. She's the group's pet, along with Luna, and many times is treated like a dog, for funny purposes. She loves Luna and every single morning gives him ramune. Very popular among girls.

She's usually made fun of inside the group, specially by Corona and Iris. The girls in the group even touch and kiss her to make her embarrassed, and after the usual tsukommi, she doesn't seem to care much. Like Luna, she's pure in romantic subjects and get flustered quickly. She loves the girls just as much she loves Luna, and because of that she doesn't want to break the group apart by starting a romantic relationship with Luna.

A funny and energetic girl and Reyla's older twin. Probably the group's closest to a normal girl, if a normal girl goes following her friends on dates while wearing a giant squirrel costume in the middle of the summer. She works in her parent's american style diner Cherry Crown Diner as waitress and poster girl. She and her sister are best friends with Corona, Ramune and Luna. Every school morning she and her sister bring breakfast to them, usually by throwing the food at them.

She's very honest and pure, which is why she's called Crystal Heart, contrary to her sister, who is mysterious and seems to be always be planning something. When Ramune is not around or not able to make the tsukkomis, Iris is the one to take up the task.

She loves Luna, but also loves the group, and doesn't wants the group to disband because of a fight for Luna's love. When her sister proposes the "Harem Plan", she agrees happily, as long everyone on the group is happy too.
