Tarō Hitsuji (羊太郎, Hitsuji Tarō/Tarou) is the author of the Akashic Records of Bastard Magic Instructor Light Novel and Memory Records of Bastard Magic Instructor series.
In order to get Celica back, Glen and Sistina desperately try to chase her down. But in the middle of this, the two suddenly go back to the past, 4000 years ago. Indeed, the name of this time is the Remarkable Magic Civilization Era. This era had various magics born during it, so the magicians were very strong. However, this civilization was mysteriously destroyed, and a lot of magic was lost as a result. Why this Remarkable Magic Civilization Era was decimated, scholars, philosophers—no one really knows. After all, the dead can't speak. But there is one piece of evidence: the fairytale, "Melugalis's Magician." According to this book, there was a terrifying demon king in the past, but a certain magician defeated them and returned the world back to peace. Of course, no one really believes in it, but what's really the truth? Thus, it is now time for Glen to know Celica's true identity, the truth of the past, and his hidden magic. ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー This was a very wonderful novel! Finally, Taro Hitsuji revealed this series' big mysteries! Without going against expectations, they all became great developments. Before, this series gave all sorts of hints, but it still hid the truth. For example, Nameless always helps Glen and the others, but her motives are unknown. For example, the cause of Celica's immortal body and the reason for her overwhelming magic are still unknown. For example, the reason why the invincible Magic Era fell is also unknown.
Then, this book brilliantly answered all these mysteries. The moment that Taro Hitsuji made these mysteries clear, I was very impressed. I thought to myself, "This series sure is amazing." So, I really look forward to the next volume!
