Broadcasting club member Shihono Kobayashi always gushes to her friend Aoto Endou about MagiKoi, an otome game where protagonist Fiene attends the Royal Academy of Magic. But despite the colorful cast, the one character Kobayashi is most obsessed with is the villainess Lieselotte Riefenstahl. Contrary to her rude remarks toward Fiene, Lieselotte longs to be her friend. Lieselotte is also deeply in love with her own fiancé, Prince Siegwald Fitzenhagen—the game's main love interest. Unfortunately, in almost every route, Lieselotte is doomed to a tragic end. Kobayashi manages to convince Endou to play MagiKoi to practice his speaking skills. What begins as a normal playthrough turns extraordinary when Siegwald suddenly hears the players' voices inside the game! Now labeled as "gods," Endou and Kobayashi use their comments and analyses to save their beloved tsundere villainess from her fated demise.

Despite Kyouko Honda's tragic death, her vivid memory lives on, providing guidance through times of hardship to her close ones. However, Kyouko was not always the wise and radiant person that she is fondly remembered as in the present day. Feeling deserted by her own family and rejected by society, a young Kyouko abandons stability for a life of delinquency, jeopardizing her education and future. Fortunately, her descent into despair is interrupted by a fateful encounter with her husband-to-be Katsuya, who has recently started his teaching internship at her school.

As the two grow closer together, Kyouko opens her tormented heart to him and, along with it, a door to new horizons.

When aliens known as the Oni threaten to invade the Earth, they promise to leave under one condition—a randomly-chosen human must win a one-on-one game of tag against Lum, the beautiful daughter of the Oni leader. The "lucky" person selected happens to be the lustful and unlucky high schooler Ataru Moroboshi. Given 10 days to attempt to grab Lum's horns, Ataru realizes how impossible the challenge is as he is faced with Lum's extraterrestrial powers. Motivated by a promise of marriage from his childhood friend Shinobu Miyake, Ataru manages to catch Lum off guard. He mistakenly grabs hold of her bikini top first, but he eventually achieves his true goal. Although the game is over, Lum misunderstands that she is the one whom Ataru wants to marry, and she decides to move in with him. The poor student constantly tries to shake off the clingy Lum while doing his best to reconcile with his desired fiancée. After Ataru's heroic feat results in such a disastrous outcome, it is questionable whether luck will ever be on his side.
