Angelise Ikaruga Misurugi is the first princess of the noble Misurugi Empire. The kingdom has seen great power and prosperity due to the advancement of the revolutionary technology known as "Mana," an abstract bending of light that has reduced the world's problems of war and pollution to a timeless peace. However, not all are blessed with the ability to wield Mana. Those who cannot are labeled "Norma," outcasts of society who are considered a threat to civilization and live under constant persecution, and Angelise herself is one of many who want the Norma exterminated. But as Angelise's sixteenth birthday commences, it is discovered in a shocking revelation that she is actually a Norma. Chaos ensues, the public is outraged, and the once adored princess is exiled to Arzenal: a remote military base where Normas are forced into conscription. Now, the former royal must adapt to a harsh and vastly different lifestyle; piloting mechanical robots known as "Paramail" to fend off large, devastating beasts referred to as DRAGONs. However, a sinister truth about these savage creatures threatens to change everything.

On his way to a convenience store, Kazuya Shiina tries to defend two young girls from an armed assailant, only to end up getting stabbed himself and dying on the spot. This good deed allows him to be reborn with all his memories in another world as Cain von Silford, the third son of a margrave. When Cain turns five, a baptismal ceremony in the church grants him an audience to the seven gods who preside over the world. Not only do the gods fill him in on the circumstances of his reincarnation, but they also give Cain their respective divine protections—allowing him to use cheat-like abilities in swordsmanship, magic, and many other aspects. With these blessings, Cain sets out to live a fulfilling life that he deems a dream come true. However, it soon becomes clear that the gods have more plans for him than just a haphazard bestowal of overwhelming power.

Having reached the pinnacle of human potential, Varvatos was so powerful that the rest of humankind began calling him the Demon Lord, both fearing and respecting his overwhelming influence. As a result, he felt alienated from his fellow humans, leading him to desire true companionship—an equal he could call a friend.

Unfortunately, he realizes that even after weakening himself, his strength still overshadows everyone in this era. Moreover, his lack of social skills bars him from achieving his goal of making friends. But worst of all, the repercussions of suddenly abandoning his former position have begun to bite him back in some of the most unimaginable ways possible.

Love has never really been a concern for Mitsuyoshi Tada, and as the aspiring photographer enters his second year of high school, it truthfully could not be further from his mind. However, things just might change after he meets a bright and bubbly foreigner named Teresa Wagner while he was taking pictures of a cherry blossom tree. Nevertheless, after she asks him to photograph her, the two soon separate, only to meet each other again twice more that same day. Finding Teresa just as she is caught in a sudden downpour, Tada invites her to his family's coffee shop to dry off. There, she explains that she was separated from her traveling companion, a no-nonsense redhead named Alexandra "Alec" Magritte. When Alec reunites with Teresa shortly after, they say their goodbyes, expecting to part ways for good—but the two unexpectedly show up as transfer students in his class the next day. Teresa and Alec quickly get used to their lives at Koinohoshi High School and decide to join Tada in the photography club, along with his narcissistic friend Kaoru Ijuuin, the idol-obsessed Hajime Sugimoto, the serious class rep Hinako Hasegawa, and the dog-like Kentarou Yamashita. With these two peculiar additions to his equally eccentric group of friends, Tada's second year of high school is about to get even livelier, and he might need to start rethinking his approach to love.
