Naota Nandaba is an ordinary sixth grader living in a city where nothing amazing ever seems to happen. After his brother Tasuku leaves town to play baseball in America, Naota takes it upon himself to look after everything Tasuku left behind—from his top bunk bed to his ex-girlfriend Mamimi Samejima, who hasn't stopped clinging to Naota since Tasuku left. Little does Naota know, however, that his mundane existence is on the verge of being changed forever: enter Haruko Haruhara, a Vespa-riding, bass guitar-wielding, pink-haired psychopath whose first encounter with Naota leaves him with tire tracks on his back and a giant horn on his head. Though all he wants is some peace and quiet, when Haruko takes up residence at his parents' home, Naota finds himself dragged into the heart of the greatest battle for supremacy that Earth—and quite possibly the entire universe—has ever seen.

Sequel series to Furusato Saisei: Nihon no Mukashibanashi.

As the Second World War rages on throughout Europe and the German forces advance closer to Moscow, the days of the Soviet Union seem numbered. Their only hope is the First Squad, a special unit operating within the Soviet intelligence service that consists of teenagers possessing supernatural abilities. However, the unit's sole surviving member Nadya Ruslanova suffers from memory loss and is unlikely to take part in any combat operation. The next Moment of Truth—an event that happens once every 700 years, when the actions of a single man can change the entire course of history—is rapidly approaching the Eastern Front. In hopes of breaking the stalemate at the frontlines, a German occult organization called Ahnenerbe plans to summon Baron von Wolff, a medieval knight from the Northern Crusades, and his undead army from the underworld. To prevent this from happening, First Squad must gather once again, and it is up to Nadya to bring back her deceased friends to stop the Nazis from taking over the world.

Cocona is an average middle schooler living with her grandmother. And she who has yet to decide a goal to strive for, soon met a strange girl named Papika who invites her to an organization called Flip Flap. Dragged along by the energetic stranger, Cocona finds herself in the world of Pure Illusion—a bizarre alternate dimension—helping Papika look for crystal shards. Upon completing their mission, Papika and Cocona are sent to yet another world in Pure Illusion. As a dangerous creature besets them, the girls use their crystals to transform into magical girls: Cocona into Pure Blade, and Papika into Pure Barrier. But as they try to defeat the creature before them, three others with powers from a rival organization enter the fray and slay the creature, taking with them a fragment left behind from its body. Afterward, the girls realize that to stand a chance against their rivals and the creatures in Pure Illusion, they must learn to work together and synchronize their feelings in order to transform more effectively.
