Two twin cities named Otova ("the sound of wings") lie in opposite hemispheres… In one city a familiar Christmas story unfolds – high‑school senior Hiro has left home and lives alone, earning money by drawing manga. Alas, the bohemian lifestyle does not help his academic success. A creative spirit like his needs feminine care and gentle guidance, which Kei, the hero"s childhood friend, is firmly convinced of. She does not like that her "big brother" has fallen into the web of a beautiful, outspoken classmate Miyako; then there"s some Tsutumi, a film‑art fan, who keeps offering suggestions, and Midzuki"s friend only wants to swap girl manga. What kind of manga when the "brother" is taken away?! And on the other side of the world, where summer reigns, dreamer Renji"s fate brings him together with a strange girl who has a bandage over her left eye. But after a pleasant conversation, the next day he suddenly hears from her: "Sorry, have we met before?" Tihiro, his new acquaintance, has suffered a terrible misfortune. No one can help her, not even the mysterious guardian Himura, who seems to possess powers and knowledge beyond a mere mortal"s reach. After all, there are no miracles in the world; only chance, regularity, and each person"s actions. But is that really so? Is there a deeper meaning behind Himura"s words, the guardian of the southern city, and Yuko"s words, the guardian of the northern city? "The History of Memories" will tell you…
